Pin accuracy

Hacker houses mostly do not publish addresses — they hand them out on RSVP. Those pins are neighborhood-level and deliberately so; use the link, not the coordinates. Public venues, cafés and parks are accurate to the block. Houses also dissolve and reform constantly: treat every name here as a lead to verify this week, not a booking.

§02

SF: The Grid

Geography first

Three facts and the city makes sense.

Market Street is the seam. It runs diagonally from the Ferry Building (northeast, on the water) down to the Castro (southwest). North of Market: the old city — Financial District, Chinatown, North Beach, Nob Hill, Union Square. Small blocks, steep. South of Market ("SoMa"): warehouses turned offices, huge blocks, flat, dead at night. Every address you're given gets described relative to Market.
Twin Peaks splits the weather. The hills in the middle stop the ocean fog. East of them (Mission, SoMa, Potrero): sunny, ten degrees warmer. West (Sunset, Richmond): grey and windy. It can be 22°C in Dolores Park and 13°C at Ocean Beach at the same moment, twenty minutes apart.
Hills lie to you. Maps says fifteen minutes; it doesn't mention that four of them are a 20% grade.

Neighborhoods, one line each

Neighborhood	What it is	Why you go
Hayes Valley	Small, walkable, boutiques around a green square. Nicknamed "Cerebral Valley" because so much of the AI world lives and drinks here.	Your default base.
The Mission	Historically Latino, heavily gentrified, sunniest and most alive part of the city. Valencia is the spine, Dolores Park the lawn.	Food, nightlife, Saturdays.
SoMa	South of Market. Warehouses, offices, convention centers, clubs. Empty and grim after 20:00.	Daytime meetings, big events, techno.
Castro	The historic centre of LGBTQ+ political life in America. Rainbow crosswalks, the Castro Theatre, real history in the sidewalk.	Nightlife, the walk, the history.
North Beach	Italian old city and Beat Generation ground zero — City Lights, Vesuvio next door.	Bars, espresso, best short walk in SF.
Chinatown	Oldest in North America and a functioning neighborhood, not a set. Before 09:00 you see it work.	Dim sum, morning markets, cheap food.
Nob / Russian Hill	Old money on the steepest hills. Grace Cathedral, Lombard's crooked block, Polk St bars below.	Views, cable car, one good dinner.
Marina	Young, sunny, moneyed, post-college. Chestnut St. The stereotype is real and locals joke about it.	Crissy Field running, brunch.
Richmond / Sunset	The foggy west. Quiet, residential, and where the great cheap Asian food is — Clement St and Irving St.	Cheap food, Ocean Beach, the park.
Potrero / Dogpatch	Sunny converted industrial on the water. Quiet, increasingly where offices are.	Calmer coffee, waterfront walk.
Bernal Heights	Village on a hill, one main street (Cortland). Bernal Hill has the best free 360° in the city.	Sunset, dogs, a quiet Sunday.
Presidio	A former army base that is now a giant park at the foot of the Golden Gate Bridge.	Trails, hidden art, the bridge.
Tenderloin	Roughly Market–Van Ness–Geary–Mason. Concentrated poverty, open drug use, the city's hardest square mile.	Don't walk it at night.

Weather trap

SF has no summer. June–August is the coldest, foggiest, windiest stretch of the year. September and October are the actual summer — warm, clear, still. You're arriving at the good part. Still bring a real jacket: nights sit at 11–13°C year-round and the wind makes it worse.

§03

SF: The Houses

Hacker houses & coliving

This is the layer that makes SF different from every other city: a few hundred people live in houses organised around building things, and those houses run the events, hold the group chats, and are where the introductions come from. Living in one collapses six months of networking into three weeks. All of these are on the map under Houses.

The institutions

Name	What it is	Cost	Way in
Frontier Tower	A 16-floor "vertical village" at 995 Market St for frontier tech — AI, crypto, biotech, robotics, neurotech, longevity, arts. Runs 3+ events a day: hackathons, demo nights, community dinners. Event spaces are the Spaceship (floor 2) and the Lounge (floor 16). Opened in the former Burning Man HQ; hit its first anniversary in April 2026.	Events free	Just go — the public calendar is luma.com/frontiertower. There's an 8-week residency for 10 startups (equity-based): frontiertower.io/residency
Founders Inc	42,000 sq ft campus at Fort Mason with a hardware lab and media studio. The most walk-in-friendly space in the city. Runs Night Hack (five hours to ship something real) and Canopy, a five-week intensive. Explicitly does not take pitch decks — they invite you to build in the lab for one to two weeks and decide from execution.	Free / equity	f.inc/apply · events at luma.com/fdotinc
AGI House SF	A mansion that functions as a residency plus hackathon engine for AI researchers and founders. 80+ build-a-thons run, up to five events a week, some co-run with frontier labs. Lovable and Perplexity have roots in events here.	$2k–10k/mo	Attend a hackathon first — that's the front door, and sleeping over at multi-day events is normal. agihouse.ai
HF0	The most selective founder residency in the world: 12 weeks live-in, roughly 10 teams per cohort out of thousands of applicants, run out of a converted Hayes Valley hotel. Housing, food and laundry handled so you only build.	Funded	An application, not a crash. The Fall 2026 deadline was 1 Aug 2026 — already passed, so target the next cohort. hf0.com/apply
The Residency	Nine startup homes across SF with a curated community — group dinners, fitness programming and demo days built into the rent. The most "just move in" of the serious options, and the most likely to have a short stay.	Rent	Apply through their site; rooms open when residents leave for batches.
Foundry	Coliving residency for founders — dinners, fitness, demo days. 100+ founders and engineers have lived there, and the stated pattern is that people stay longer than they planned.	Rent	foundry.today
Hive Coliving	Multi-house coliving aimed squarely at techpreneurs and hackers: furnished rooms, utilities included, communal kitchens, a built-in community. Less selective, more available.	Rent	hivecolivingsf.com
Urbanests	A coliving operator running properties positioned in SoMa, Mission Bay and Dogpatch specifically for the current AI influx. Corporate rather than communal, but rooms exist when the cool houses are full.	Rent	urbanests.com
homes—less	Multi-house coliving network pitched at tech people, marketed on rental perks. Worth a look if you want a month rather than a week.	Rent	homes-less.com
hackermap	A directory of hacker houses and coliving filterable by type — HF0, AI/tech, coliving, research, incubator, network, web3. The single best starting index, though it's JS-driven so you have to browse it live.	—	hackerhouses.org

The pattern behind all of them

Every one of these has a public event that anyone can attend and a private housing decision made by people you meet at it. So the sequence is never "email the house." It's: show up to the demo night, be useful, meet three residents, ask at the end of the night. Frontier Tower alone runs three events a day — you can be inside the layer within 48 hours of landing.

One geographic note

Frontier Tower is at 995 Market Street, which puts the single best event calendar in the city on the edge of the roughest stretch of mid-Market. Walking there in daylight is unremarkable. Leaving at 23:00 on foot is not — order the car from inside the lobby.

§04

SF: Free Board

Sleeping on nothing

Crashing in SF is normal and there's an established culture around it — but it's a culture of exchange, not of asking. Nobody gives a stranger a couch. Plenty of people give one to someone who's building something and shows up useful. Line it up two to four weeks out.

#	Play	Cost	How it really works
1	Hackathons	$0	The best free-housing hack in the city and nobody frames it that way. Multi-day AI hackathons run most weekends — sleep on site, all meals, and you leave having met a hundred builders. AGI House alone runs up to five events a week; Founders Inc runs Night Hack. Two a month is eight free nights and your network.
2	Ask in public	$0	Post on X and in every group chat: "In SF [dates], building [specific thing], looking for a couch. I'll cook, I'll help with your launch, I'll run your demo night." Works here because hosting an interesting builder is mildly high-status. Attach proof of work, not a plea.
3	Hacker houses	$0–80/night	Rooms open constantly as residents leave for batches. Short crashes are routine. See §03 — you get in through the event, not the inbox.
4	House-sitting	~$150/yr	TrustedHousesitters and similar: annual membership, then free stays for feeding someone's cat. High SF demand, badly under-used by tech people. Build the profile before you need it — reviews are the currency.
5	Volunteer at events	$0	Conferences trade free badges and occasionally housing for shifts. Four hours on the door for three days of access. Ask organisers directly a month out; they're always short.
6	Room-splitting	50%	During conference weeks, "anyone want to split a room?" fills group chats within hours. Legitimate and common — the channels are listed below.
7	Hostels	$50–80	The paid floor. HI Fisherman's Wharf is inside a former army building at Fort Mason with a bay view — nothing like a city hostel, and a four-minute walk from Founders Inc. Green Tortoise in North Beach is the social one, free breakfast.
8	Sublets	$900–1800/mo	For weeks rather than days, Craigslist SF is genuinely still the best market, plus the big Facebook sublet groups. A month in a shared flat beats twelve nights in a hotel on every axis.

Room splitting — where to actually check

Two different problems, two different sets of channels. Splitting a room means halving a hotel or Airbnb someone already booked, usually for a few nights around a busy week. Finding a room means a sublet or a share for weeks. Don't post in the wrong places — a "splitting an Airbnb Tue–Fri" ask dies instantly on Craigslist and lands in ten minutes in a group chat.

Channel	Best for	How it works
Group chats	Splitting, nights	The highest-yield channel by a distance. Signal / Telegram / WhatsApp founder chats. Posts get answered in minutes because everyone in them is doing the same maths. You need one intro to get into one chat — ask at your first event, it's a normal request.
Event Slack / Discord	Splitting, conference weeks	Almost every conference and hackathon runs a `#housing`, `#roomshare` or `#logistics` channel, and most people never open it. Join the Slack the day you register, not the week you fly.
Luma event pages	Splitting, hackathons	Multi-day events have a discussion/chat tab on the event page. Post there — you're matching with people who are provably attending the same thing you are.
X / Twitter	Splitting, both	Search "SF" + "split an Airbnb" or "room share" filtered to the last week, and post your own with dates in the first line. During big weeks this genuinely works within a day.
Craigslist SF	Rooms, weeks	Still the best market in San Francisco specifically, which surprises people. Use rooms & shares and sublets / temporary. Post as well as browse — a well-written "looking for" gets replies.
Facebook groups	Rooms, weeks	The big SF housing / rooms / sublets groups are large and active, and they're where short sublets that never hit Craigslist get posted. Join before you need them; some have approval queues of several days.
Roommate apps	Rooms, months	SpareRoom, Roomi, Diggz. Structured, slower, better for a month than a week.
House waitlists	Rooms, weeks	The Residency, Hive, Foundry and the coliving operators in §03 all keep waitlists that move when residents leave for batches. Get on several — it costs nothing and you only need one to open.
Reddit	Last resort	r/sanfrancisco and r/AskSF have rules about housing posts and low signal for short stays. Useful for questions, not for beds.
The person next to you	Splitting, tonight	Underrated to the point of being a cheat code: at the first event, ask people "where are you staying?" Half the room is a visitor with a booking that has a spare bed and a cost they'd rather halve.

The post that gets answered

"SF, Tue 8 – Sun 13. Looking to split a room / Airbnb, up to $X/night. I'm [one clause — what you're building]. Early sleeper, out most of the day, easy houseguest. Happy to book and have you join me, or join yours."

Dates in the first line, budget as a number, one sentence on who you are, and an explicit offer to be the one who books. Skip the pleasantries. The offer to book is what makes strangers reply — it turns you from a risk into a solution.

Timing

Room-share posts cluster two to three weeks before a busy week and dry up about three days out, when everyone has sorted themselves. Post early even if your plans aren't firm — you can always decline. Posting the night before you fly is how people end up paying rack rate.

What you're actually trading

Free housing here is paid for in labour and interestingness. Offers that land: cook dinner twice a week, run their demo night, fix their site, build the thing they keep complaining about, film and edit their event. Offers that don't: "I'll be quiet and clean up after myself." Everyone says that.

The one line not to cross

Splitting a room someone booked is normal. Sneaking into hotels or riding someone else's key is not — it's the one move that gets you removed and, in a scene this small and this chatty, attached to your name. Everything above gets a free bed without that.

§05

SF: Broke Mode

Eat, work, live on nearly zero

SF is one of the most expensive cities on earth and also one of the easiest to run at near-zero cost, because the tech economy subsidises food, desks and entertainment to get access to people. That's you.

Free dinner, five nights a week

Not a joke or an edge case. Luma events in SF almost always feed you: pizza and beer at meetups, catering at demo nights, full meals at hackathons, open bars at launch parties. RSVP to two things a night, eat at the first, work the room at the second. Frontier Tower's three-a-day calendar makes this trivially easy.

Daytime backstop: Chinatown bakeries ($2 buns), taquerias ($12 and enormous), Clement and Irving lunches under $15, grocery hot bars.

Free desks

SF Public Library, Main Branch — beautiful building, fast wifi, real desks, no questions.
Founders Inc — open floor, walk in.
Salesforce Park — 5.4 acres on a roof, free, free gondola up.
Hotel lobbies downtown — seating and outlets nobody polices.
Cafés — one coffee buys three hours. That's the deal.

The city is free anyway

Almost everything worth doing in §11 costs nothing: Lands End, the Presidio, every viewpoint, Golden Gate Park, Ocean Beach, the de Young's observation tower, Grace Cathedral, Musée Mécanique, City Lights, Dolores Park on a Saturday. Most museums run free days.

Free fitness, and showers

Run clubs — free, weekly, one of the best social entry points for someone who knows nobody.
Lyon Street Steps — the outdoor gym locals actually use.
Showers — chained gym trial passes, a hostel night, or the house you're crashing at.

Movement for nothing

Walk everything under two miles. Bay Wheels day pass is a few dollars and flattens the hills. Muni is $2.75. Skip ride-hail except after 23:00, where it's a safety expense.

A hard week in SF: $0 housing, $0 dinners, $2.75/day transit, one $6 coffee to rent a table.

§06

SF: Ground Rules

Culture & passing as local

Not New York, definitively not LA. Status here isn't money, looks or social connections — it's what you're building and what you actually understand.

RULE 01

"What do you do?" arrives in 90 seconds. Not rude — it's the local handshake. Have a twelve-word answer ending in a hook, not a job title.

RULE 02

Under-dress. Good hoodie or technical shell, decent shoes. A blazer reads as "sales" and costs you a beat.

RULE 03

Cynicism is the lowest-status posture here. Being the smart guy explaining why it won't work makes you forgettable.

RULE 04

Strangers take meetings. A short, specific, non-selling cold message lands far more often than anywhere else. The biggest arbitrage of being here.

RULE 05

Flaking is endemic. Assume 30% no-show; confirm every 1:1 that morning. Don't be the flake — reliability is rare enough to be a differentiator.

RULE 06

Nobody asks where you went to school. They ask what you shipped. A working demo outranks a résumé, a title and a deck at once.

RULE 07

Everyone is from somewhere else. "How long have you been here?" beats "are you from here?"

RULE 08

The city sleeps early. Dinner 18:30–19:00, weeknight bars thin by 23:00. Real nights are Thursday to Saturday.

The tells

Marks you as new

"San Fran." "Frisco" is worse and people visibly react.
Shorts, then buying a fleece at a tourist stall by 15:00. The classic arc.
Taking the cable car as actual transport.
Standing in the street to photograph the Painted Ladies.
Calling BART "the subway," or expecting it to go where you're going.
Renting a car for a city stay.
Being audibly shocked at the bill. Everyone is; nobody says it.
Going north of Bay Street for any reason.

Reads as local

A shell jacket in August and a second layer in the bag.
"The city" meaning SF, and only SF.
Naming the fog. It's Karl. People ask whether Karl is in.
Knowing instantly which side of Market you're on.
Ordering at the taqueria without reading the menu.
A Bay Wheels e-bike instead of an Uber under three miles.
Complaining about Muni with genuine affection.
Eating dinner at 18:30 and meaning it.
Knowing the Wiggle exists (§19).

The hard part

Homelessness, untreated mental illness and open drug use are visible and severe, concentrated in the Tenderloin, mid-Market and parts of SoMa. You'll see things on day one you haven't seen before. Don't film it, and don't moralize about it to locals — they've lived inside that argument for a decade. Keep walking, keep normal awareness, route around the blocks in §19.

The one phrase that works

"Want to see it?" — then open your laptop. In a city where everyone is describing something, being the person who shows it is a structural advantage. Demo loaded, offline-capable, under 90 seconds, rehearsed enough that bad wifi can't kill it.

§07

SF: Movement

Getting around

Mode	Cost	Use it for
Bay Wheels e-bike	~$4–8	Best value in the city and the local default. Flattens the hills, beats cars in traffic. In the Lyft app. Most 1–3 mile hops.
Muni	$2.75	Buses and light rail. Clipper card in Apple Wallet, tap. Useful lines: N-Judah (downtown↔beach), 22 Fillmore (crosstown), 14 Mission.
Waymo	$15–35	Driverless, app-based, city-wide, genuinely a local default now. Do it once for the experience, then keep doing it because there's no small talk.
Uber / Lyft	$15–35	Brutal surge the moment an event lets out — walk two blocks before ordering.
BART	$2.50–10	Regional rail, not a metro. Market and Mission, plus the airport and East Bay. Grim late.
SFO → city	$10 / $65	BART 30 min for ~$10, drops you on Market. Uber 25–45 min for $55–80.
Rental car	Don't	Only for a day trip out of the city, returned same day.

Bipping

Car break-ins are so routine they have a local verb. Never leave anything visible in a parked car — not a jacket, not a cable, not an empty bag. Locals leave the glove box hanging open to prove it's empty.

Planning rule: cluster meetings by neighborhood. Crossing the city costs 25–40 minutes each way; doing it four times is your whole afternoon.

§08

SF: The Scene

Where the work happens

Two San Franciscos: the visible one of conferences and offices, and the real one of group chats, house dinners and demo nights. The second is where everything happens and it takes about ten days to get into — less if you use §03.

Event layer, ranked by signal

Rank	Channel	How to get in
1	Group chats	Signal, Telegram, WhatsApp. The actual layer — where couches, room-splits, unlisted parties and the first freelance gigs get offered. Ask everyone: "what group chats are you in?" Normal question here.
2	Frontier Tower	Three-plus events a day in one building. If you did nothing else, this calendar alone would fill your trip. luma.com/frontiertower
3	Partiful	House parties and dinners. Follow hosts and their networks open to you.
4	Luma	The event OS of SF and your free dinner calendar. Start with the GenAI SF calendar and Cerebral Valley; subscribe rather than search.
5	Hackathons	Free, fed, often free to sleep at, and the highest ratio of people-met to dollars-spent of anything in the city.
6	AI Tinkerers SF	Free monthly builder meetup, high builder-to-talker ratio. Get on the list early; it fills.
7	Big conferences	Expensive and noisy. Skip the badge, work the side events — someone always publishes a side-event sheet.

Rooms you can work in

Shack15 — upstairs in the Ferry Building, bay view, arguably the best networking room in the city. Membership, but guests get in. Being someone's guest is a week-one goal.
Founders Inc — Fort Mason, open floor, event-heavy, friendliest front door in SF.
Frontier Tower — 995 Market, sixteen floors of it.
South Park Commons — a community for people between things. Hard to join, high quality.
Cafés as offices — Réveille (Hayes), Ritual (Valencia + Hayes), Sightglass (7th St + 20th St), Tartine Manufactory, Four Barrel, Andytown (Sunset). Pick two and go daily at the same hour. In three days you're a face; in a week you're in a conversation.

The bar for a pitch

Demo beats deck, always. Nobody will read your deck. If you can put a working thing on a screen within two minutes of "what are you building?", you're in the top decile of conversations that person has all night.

§09

SF: People

Who to find, and how

Don't try to meet impressive people. Fill seven roles. A network with all seven compounds; forty impressive strangers does nothing.

ROLE 01 · CONNECTOR

Hosts dinners, knows everyone, introduces for sport. You'll spot them when three unrelated people name them unprompted. Worth thirty cold DMs.

ROLE 02 · HOST

Runs a house, a dinner, a meetup. Their list is a standing invitation — and per §04, sometimes a bed. Offer to help run the thing.

ROLE 03 · OPERATOR

A founder or GTM person 12–24 months ahead of you. Most useful tactical advice you'll get, most freely given.

ROLE 04 · PEER

Someone shipping at your level right now. Co-work weekly. Accountability and morale matter more than they sound like they should.

ROLE 05 · INSIDER

Works at a frontier lab. Not for secrets — for calibration on what's six months out, so you don't build something about to be free.

ROLE 06 · BUYER

An actual person in your ICP with a budget. Every trip should produce at least three. Talk about their problem, not your product.

ROLE 07 · OLD-TIMER

Ten-plus years here. Tells you which parts of the current mania are new and which they've watched twice. Invaluable as a filter.

Cerebral ValleyAI Tinkerers SFlu.ma/genai-sf Frontier TowerFounders IncShack15 South Park CommonsAGI HouseThe SF Standard

The cold message that works

Template

"Saw [specific thing they made or said] — I'm doing [one clause about your thing] and hit the same wall with [specific problem]. In SF until [date]. Coffee near [their neighborhood] Tue or Thu? Happy to just answer questions about [thing you know that they don't]."

Four lines, no preamble, one ask, nothing to sell. It works because it proves five minutes of homework, it's bounded in time, it names a place, and it offers something. Delete any sentence about how impressive they are.

The actual alpha

Same-night follow-up. Every person you meet gets one message before you sleep, referencing something specific they said, with one concrete next step. Second touch inside seven days or the connection is dead. Almost nobody does this, which is exactly why it works.

§10

SF: The Routine

A day that compounds

The mistake visitors make is treating the trip as a series of events. Run a fixed daily shape and slot the city into it.

07:00Up and movingRun the Embarcadero, Crissy Field or the Dolores loop. Better: a run club — free, weekly, a real social entry point.

08:30Café A — deep workSame café, same table, same hour, daily. Three hours of your hardest work before the city wakes. The trip fails if you only network.

12:00Lunch is a meetingNever eat alone. Lunch is easier to get than coffee — it's a slot people already blocked.

13:30Meeting blockTwo or three 1:1s, one neighborhood, walk between them. Calls in the gaps.

16:30Café B — ship somethingLower energy, higher volume. Follow-ups from lunch, one small thing shipped.

17:45Event #1Arrive at the stated start — the first twenty minutes is the only window where people are meetable. Eat here. Leave when it turns into a talk.

19:30Dinner or Event #2Two events a night is the sustainable maximum. Three is a blur you won't remember.

22:00Follow-ups. All of them.Twenty minutes, every person from today, one message each, before you sleep. The whole game, and the step everyone skips.

The week has a shape too

Day	What it's for
Monday	Dead night. Pure work day. Line up the week, send the asks.
Tuesday	Events begin. Good for 1:1s — calendars aren't full yet.
Wednesday	Peak weeknight. Most meetups and demo nights.
Thursday	The big one. Dinners, parties, best rooms. Protect this night.
Friday	Parties, then the city empties for Tahoe and Marin.
Saturday	Daytime social: hikes, Dolores, markets. Or a hackathon. Night is §13.
Sunday	SF at its best and quietest. Farmers market, Golden Gate Park, a long walk. Schedule zero work.

Per week: 3–5 events, 8–12 one-on-ones, one thing shipped, one invoice sent.

§11

SF: Must See

Ranked, with time and cost

Ranked by what you'd regret missing, not by what's famous. Almost all of tier one is free, and most of it is outdoors — that's the honest shape of San Francisco. If you only get three, take the first three.

Tier 1 — do these or you didn't go

#	Thing	Time	Cost	When & why
1	Lands End → Sutro Baths	2h	Free	Morning, fog or sun — both are good, and the fog is arguably better. Cliff trail on the city's northwest corner: the ruins of a vast Victorian bathhouse in the surf, cypress tunnels, a stone labyrinth on the headland, and the bridge appearing and disappearing. The single best thing in San Francisco.
2	Bike the Golden Gate	4h	~$50	Start 13:00. Rent in the Presidio, cross the bridge, descend into Sausalito, ferry back with Alcatraz on one side and the skyline growing on the other. It's the cliché and it completely earns it. The ferry ride alone is the best 30 minutes of transit in California.
3	Dolores Park, sunny afternoon	2h	Free	Saturday or Sunday from about 14:00. This is the city's living room and the closest thing to a portrait of who lives here. Bring nothing; buy from the vendors walking the hill.
4	de Young observation tower	20 min	Free	Any clear hour. A lift to a 360° glass floor over Golden Gate Park and the ocean. You do not need a museum ticket — walk in and go up. Best free view in the city and almost nobody knows.
5	Golden hour, Tank Hill	1h	Free	Arrive 40 minutes before sunset. Ten minutes of climbing above the Castro for the whole city turning orange, usually with fewer than a dozen people there. Bernal Hill is the alternative and better for sunrise.
6	A Mission burrito	30 min	$16	La Taqueria (no rice, purist) or El Farolito (everything, open till 02:45). Pick a side. People argue about this sincerely and it's a decent conversational opener with anyone who's lived here.
7	North Beach at dusk	1.5h	$15	City Lights Books → Vesuvio next door → espresso on Columbus → up the Filbert Steps to Coit Tower. City Lights published Ginsberg's Howl in 1956 and won the obscenity trial; Vesuvio hasn't changed since. The best short walk in the city.
8	Ferry Building, Saturday	1.5h	$25	09:00–13:00 for the farmers market, which spills around the whole building. Oysters at the bar inside. Then walk the Embarcadero south with the bay on your left.
9	Chinatown before 09:00	1h	$8	Weekday morning, when it's a working neighborhood doing its shopping rather than a photo opportunity. Oldest Chinatown in North America. Dim sum takeaway from a counter with a queue.
10	A Waymo, at night	15 min	$18	Get in an empty car and let it drive you across the city. It's genuinely one of the few things in San Francisco you can't do in many other places yet, and it stops feeling strange faster than you'd expect.

Tier 2 — if you have the days

The Presidio. Battery to Bluffs down to Marshall Beach for the bridge from underneath; Andy Goldsworthy's Spire and Wood Line hidden in the eucalyptus; Tunnel Tops for the framed view.
Alcatraz, night tour. The one paid attraction that's worth it. Book several weeks out — the night tour sells first.
Exploratorium after dark. Hands-on science museum on a pier with an adults-only evening. A genuinely great date.
Grace Cathedral. Free, on Nob Hill, with a labyrinth inlaid in the floor that you're meant to walk.
SFMOMA. Enormous; the ground floor is free.
Ocean Beach fire at sunset. Legal in the designated pits, freezing, unforgettable. Bring wood and more layers than you think.

Golden Gate Park properly. Japanese Tea Garden, the botanical garden, a bison paddock, and JFK Promenade closed to cars.
Cable car, once. Powell–Hyde line, hang off the side, get off at the top. Then never again — it's a ride, not transport.
Twin Peaks at 06:30. The postcard view without the tour buses, and the fog often pours over the ridge while you watch.
Corona Heights. Raw red rock and the sharpest city view, five minutes from the Castro.
Musée Mécanique. Free, hundreds of working antique coin-op machines. The one reason to go to the Wharf.
The Castro. Not a sight so much as a place to walk slowly — the sidewalk plaques, the rainbow crosswalks, the history under your feet.

Tier 3 — the only-in-SF oddities

This is the tier that separates people who visited from people who looked. All free, all strange, none of them on a tour bus route.

MARINA

The Wave Organ. An acoustic sculpture built into a jetty out of demolished-cemetery marble, played by the tide through twenty-five pipes. Best at high tide. You put your ear to a pipe and the bay makes a noise.

INNER SUNSET

16th Avenue Tiled Steps. 163 steps covered in a mosaic that runs from sea to stars, made by 300 neighbors. Climb them, then keep going up to Grandview Park for a view most locals haven't had.

UNDER THE BRIDGE

Fort Point. A Civil War brick fort tucked directly beneath the southern anchorage of the Golden Gate Bridge. Free, echoing, and the spot where Kim Novak jumps in Vertigo.

MISSION

Balmy & Clarion Alleys. Two side streets given over entirely to murals, painted over and repainted for forty years. The densest political art in the city and it changes constantly.

LANDS END

Camera Obscura. A 1946 seaside oddity: a darkened room with a rotating lens on the roof projecting a live image of the cliffs onto a parabolic dish. Same trick Leonardo described, still working.

FORT MASON

The Interval at Long Now. A bar and library run by the foundation building a clock designed to run for 10,000 years. A prototype is in the room. The drinks are good and the whole place is a thesis.

CASTRO

Seward Street Slides. Two long concrete slides down a hillside in a residential pocket, designed by a fourteen-year-old in 1973. Bring a flattened cardboard box; there's usually one at the top.

RICHMOND

The Columbarium. A neoclassical domed rotunda of stained glass, four storeys of urns, quiet as a held breath. It survived the ban that removed nearly every cemetery from the city.

Out of town

Muir Woods — old-growth redwoods, 45 minutes north. Reservation required, no walk-ups, book before you land.
Point Reyes — 90 minutes, cliffs, oysters, elk, and almost nobody. The best full day outside the city.
Half Moon Bay / Stinson Beach — an hour each, opposite directions, both beach days.
Napa / Sonoma — 90 minutes, needs a car and a decision about who isn't drinking.

If your dates hit one of these

Folsom Street Fair (late September) and Hardly Strictly Bluegrass (early October, free, three days, all of Golden Gate Park) are the two big ones in your window, and both are pure San Francisco in ways nothing else is. Fleet Week in October puts the Blue Angels directly over the bay. Check the dates when you book — any one of them reshapes a weekend.

Food canon

Dish	Where	Damage
Mission burrito	La Taqueria (no rice, purist) vs El Farolito (everything, open till 02:45). Pick a side; people argue sincerely.	$14–18
Dim sum	Good Mong Kok (Chinatown, cash, takeaway, a line) or Yank Sing (SoMa, sit-down, pricey).	$12–45
Oysters	Swan Oyster Depot — eighteen stools, a queue, a century-old counter. Go 10:30 on a weekday.	$40–60
Roast chicken	Zuni Café. Takes an hour, feeds two, arrives on bread salad.	$70 for two
Tea leaf salad	Burma Superstar (Clement) or Burma Love (Valencia). Burmese food is an SF speciality.	$25–35
Pastry	Arsicault (Richmond) for croissants people fly in for; Tartine (Mission) for the loaf.	$6–14
Late kitchen	Nopa until 01:00 — the one good post-midnight sit-down meal in the city.	$45–65
Cheap and great	Clement St and Irving St: Vietnamese, Chinese, Burmese, Korean, under $20.	$12–20

Skip these

Pier 39 and the sea-lion crowd, the Lombard Street queue, Union Square shopping, anything advertising a "sourdough bowl," and the Full House house.

SF: Crazy Day

Saturday · full send

Coast to bay, ~18km of movement. Exhausting, and it teaches you the whole city in a day.

06:20Battery Spencer, Marin sideTwenty minutes over the bridge. Sunrise from above the north tower. If the fog is in you get the towers floating on a white sea, which is better.

08:00Arsicault Bakery, RichmondBack over the bridge. In line by 08:15 or the almond ones are gone.

08:50Lands End trailSutro Baths ruins → Mile Rock → cliff labyrinth → Legion of Honor. Ninety minutes of cypress and Pacific with no city noise.

10:40de Young towerFree lift, 360° over park and ocean. Japanese Tea Garden across the path.

12:00Clement Street lunchDumplings, Burmese or banh mi. Fifteen dollars, thirty minutes, best value of the day.

13:15Bike the Golden Gate BridgeBike from the Presidio, cross, descend into Sausalito. Ninety minutes including the wind trying to remove your hat.

15:10Ferry back to the Ferry BuildingThirty minutes on the water, Alcatraz one side, skyline growing on the other. Stand on the back deck. Best transit ride in California.

15:50Ferry BuildingOysters and a beer, then walk the Embarcadero south with the bay on your left.

17:00Cable car up California StRide to Nob Hill. Grace Cathedral is free and open.

18:20Golden hour, Tank HillTen minutes of climbing for the whole city turning orange, with almost nobody there.

19:40Dinner in the MissionEat well and eat early, because §13 starts in an hour.

§13

SF: Crazy Night

20:30 → 06:00

SF nightlife is smaller than New York's and closes earlier, so it rewards a route. Bars stop serving at 02:00 statewide, last call 01:30.

20:30Warm-up — pick a registerTrick Dog (Mission) for a world-class cocktail bar whose menu is a different art object every six months. Zeitgeist for a gravel beer garden, cash only, no pretence. Comstock Saloon (North Beach) for 1907 with the tin ceiling intact.

21:45Live musicThe Chapel (a former mortuary, 40-foot vaulted ceiling). Bimbo's 365 (unchanged since 1931, red velvet). The Independent (best-sounding mid-size room). Great American Music Hall (1907, balconied — cab to the door). The Fillmore, where they still hand you a free poster on the way out and keep a barrel of apples at the door.

23:15Dancing — choose a laneHouse & techno: Public Works, The Great Northern, Halcyon — all within a ten-minute SoMa walk. Queer: Oasis (drag), El Rio (Mission, patio), the Castro bars.

01:30Last call — statewideNothing serves after 02:00 anywhere in California. Order at 01:25 and get outside before the surge.

02:15Late foodEl Farolito (burritos until 02:45, the great equalizer). Yamo (six stools, Burmese). Grubstake (a diner inside an old railcar).

03:00The afterhours layerWarehouse parties in SoMa and Bayview, unlisted, friend-of-a-friend — what the group chats are actually for. The one legal institution is The EndUp, which opens its Sunday-morning floor at 06:00 and has since 1973.

06:00Sunrise, Bernal HillFog pouring over the western hills while the east side goes gold. Then home.

Night safety, plainly

Cab door-to-door in the Tenderloin, mid-Market, 6th Street or Civic Center after dark. Don't use Civic Center BART late. Keep your phone out of your hand at the curb — snatch-and-ride thefts are common.

§15

LA: The Shape

Eighty-eight cities

Everything you learn in SF stops applying at the LA county line. SF is one small dense thing you can walk. LA is a constellation of neighborhoods forty minutes apart, and the organizing constraint of your entire week is traffic. Pick three zones and live in them. Trying to "do LA" is how people end up seeing freeways.

The five facts

Traffic is the schedule. Drivable: 10:00–15:00 and after 20:00. Not drivable: 07:00–10:00 and 15:00–19:30. The same twelve miles is 25 minutes or 70 depending only on when you leave. Every local plans around this and will tell you so unprompted.
You need wheels. Rent a car, or budget heavily for Uber. The Metro is better than its reputation — the E Line runs Santa Monica to Downtown and is genuinely useful, and the system is expanding hard ahead of the 2028 Olympics — but it will not cover a week of meetings across the westside.
The scene is zoned, not centralized. There is no Hayes Valley. There are five separate scenes that barely overlap, and which one you want depends entirely on what you're selling.
The weather is the same every day. Warm, dry, sunny. No fog belt, no layers. This changes the social rhythm completely: everything happens outdoors, meetings are hikes and patios, and nobody cancels for weather.
Distance is a favour. In SF, "let's grab coffee" costs someone fifteen minutes. In LA it can cost ninety. Asking someone to cross the city is a real imposition, and going to them is the single strongest signal you can send that you're serious.

The five scenes

Zone	What's there	Go if
El Segundo	"The Gundo." Hard tech, defense, aerospace, manufacturing — the fastest-growing and most distinctive scene in LA right now, built in low-rise industrial units near SpaceX in neighbouring Hawthorne. Young, intense, deeply un-glamorous, and the one part of LA that feels like early SF.	You sell to engineers. This is the highest-signal room in LA.
Santa Monica	"Silicon Beach." Consumer, SaaS, e-commerce, adtech. Snap is here. Older, more corporate, lots of coworking, walkable by LA standards.	You sell software to companies.
Venice	Creative-and-startup crossover, Abbot Kinney, agency people and founders in the same cafés. Where most of the hacker houses are.	You want to live in the scene.
DTLA / Arts District	Creative studios, some AI, the best food in the county, cheap-ish loft space, genuinely gritty at the edges.	Budget and food matter.
Culver City / Playa Vista	Media tech at scale — Amazon, Apple, HBO, Google/YouTube. Corporate campuses, not a walk-in scene.	You have a specific meeting.

LA's actual specialty

The thing LA has that SF does not is the creator–technology crossover. If what you're building touches media, content, video, creators or entertainment workflows, LA is the better market and it isn't close — those buyers are here, they have budget, and they're much easier to reach than in SF. If you're selling pure infrastructure to engineers, go to El Segundo and treat the rest of LA as a holiday.

Timing

LA Tech Week 2026 is 12–18 October — a city-wide sprawl of 100+ events from Santa Monica to Downtown, and by far the densest week of the LA year. You're going well before it. That means Luma, specific communities and warm intros will carry your week rather than an event wave; plan more 1:1s and fewer events than you would in SF, and consider that LA may be worth a second trip in October.

§16

LA: Culture & Scene

How business actually happens

Different from SF

Warmer on the surface, slower to commit. Everyone is delighted to meet you and half of them will never reply. Don't read enthusiasm as intent.
Flaking is worse than SF. Confirm the morning of and an hour before. Distance makes cancelling easy.
Image counts. Not a suit — but LA reads presentation as competence in a way SF actively doesn't. Look like you're doing well.
Nobody asks "what do you do" first. They ask what you're working on, or where you're from, and get to business later. Leading with your pitch is a misread.
Everyone has two careers. The engineer also produces. The founder also acts. This is normal and not a red flag.

Meeting formats that work

The hike. Runyon Canyon or Griffith at 08:00 is a completely standard business meeting. Accept every one.
Coffee on a patio, 10:00–11:30, before traffic rebuilds.
Erewhon. Genuinely a social institution and a meeting spot, absurd prices notwithstanding.
Lunch near their office — in LA you go to them, always. Making someone drive to you is a real cost and they'll resent it.
Beach walk at sunset for anything relationship-building.

The calendars that actually cover LA

LA's problem isn't that nothing happens — it's that events are scattered across a county and no single feed covers it. These four do most of the work:

Feed	What it covers
L.A. Tech Events	The best general LA feed — technology, startup, AI, entrepreneurship and VC events, hand-curated rather than scraped. Start here. luma.com/latechevents
AI LA	The AI-specific LA calendar. Smaller, more focused, good for finding the people rather than the crowd. luma.com/aila-events
The AI Collective	A global AI community running 100+ local chapters; the LA chapter posts here. Big-tent, high volume. luma.com/genai-collective
LA Hardware Meetup	See below — this is the El Segundo door. hardwaremeetup.substack.com
Partiful	The creative and party layer, which in LA is genuinely bigger and more useful than the meetup layer.
USC & UCLA	Both run AI research groups with public talks, and the after-drinks are consistently better than the talks deserve.

How to actually get into the Gundo

I said earlier the El Segundo scene organizes privately — that was only half right, and the other half is the most useful thing in this section. There is a public front door: the LA Hardware Meetup. It's a recurring El Segundo event that has run eighteen-plus editions, pulls 120+ hardware people a night, and features open-mic demos plus talks from operators like the CEOs of First Resonance and Pinto Robotics, with space-tech companies presenting regularly. It's part of a hardware-meetup network spanning 40+ cities and ~40,000 members.

That is a room full of exactly the people who are otherwise unreachable, and you can simply sign up. Subscribe to the newsletter, find the next El Segundo date, and go. One night there beats a month of trying to DM your way in.

The other node worth knowing: Discipulus Ventures, run out of an El Segundo warehouse, which puts cohorts of technical founders together and brings 10–20 new companies into the neighborhood every year. It's a big part of why the cluster keeps compounding, and the people it attracts have drawn attention from Lux, a16z and Point72.

The one prep task for LA

SF rewards showing up; LA punishes it. Because nothing is walkable and nothing is dense, a week in LA with no warm intros produces almost nothing. Spend two hours in SF the week before asking every person you meet: "who should I know in LA?" SF people all have LA contacts and hand them over freely. Arrive with six names and the week works. Arrive with zero and you'll see some very nice beaches.

§17

LA: Live & Eat

Houses, neighborhoods, food

Hacker houses & coliving

Name	Where	What it is	Link
Aviato Club	Venice, West Hollywood, USC/DTLA	Three houses on a "live, work, network" model. The Venice property is a bungalow-style hacker house with a large communal workspace, lounge and shared kitchen, a few blocks from the beach. The West Hollywood house ("the Oasis") is the creative one; the USC/DTLA house is two blocks from campus.	aviato.club
Haven Coliving	2478 Penmar Ave, Venice	Wellness-oriented coliving — rooftop deck, hot tub, yoga studio, coworking space, community dinners, steps from Venice Beach. Bookable in short stays, which most hacker houses aren't.	havencoliving.com
Outsite	Venice Dell	Coliving-for-remote-workers chain. Less scene, more reliability — a known quantity when you want a desk and a bed and no drama.	outsite.co

The LA hacker-house layer is genuinely thinner than SF's, and it skews Venice. If the scene is the point, stay in Venice or Santa Monica. If the Gundo is the point, there's no house culture there yet — get a cheap room in El Segundo or Manhattan Beach and drive.

Coworking — the LA equivalent of a café habit

LA has no Shack15 and no Frontier Tower. What it has instead is a deep coworking layer, and because nobody walks anywhere, the coworking space is the neighborhood — picking one and showing up daily is the closest LA gets to the SF café strategy.

Space	Where	Character
Amplify.LA	Venice, two blocks from the beach	An accelerator with coworking attached, built specifically to grow seed-stage LA startups. The most founder-dense room on the westside and the one to try first.
BLANKSPACES	Santa Monica, Venice, DTLA, Culver City, Pasadena	The most useful chain because it's everywhere you'll be. The Santa Monica Main location reads as a creative studio rather than a corporate floor, and the Venice one skews casual — standing desks, open windows, flip-flops.
Cross Campus	Santa Monica, DTLA, Pasadena, South Bay	Bigger and more corporate, with outdoor workspaces and a steady community-event calendar. Hosts a lot of the westside AI meetups.
Indiedesk	DTLA	Downtown, scrappier, with a real track record — LootCrate, VRLA and Mindshow all started there.
Beach House / MUD\WTR :gather	Santa Monica	Within a few blocks of BLANKSPACES Main; creative professionals, wellness founders, designers. Good for a change of room mid-week.
Phase Two Space	Venice / Washington Blvd	Creative-forward, casual, cheaper than the Santa Monica options.

Where to base a week

Base	Good for	Cost
Venice	Beach, walkable-ish, most houses, creative-tech crossover, best default for a first LA week.	Mid
Santa Monica	Silicon Beach meetings, Metro E line to Downtown, safest and most convenient, least interesting.	High
Silver Lake / Echo Park	The genuinely fun choice — walkable, best bars and coffee, creative crowd, 30–45 min from the westside.	Mid
DTLA / Arts District	Cheapest, most central for driving, best food access, grittiest at night.	Low
El Segundo	Only if hard tech is the entire trip. Nothing else is there.	Mid

Food — the actual reason to be in LA

LA's food is better than San Francisco's and it isn't especially close. The canon:

Tacos. Non-negotiable and best from trucks. Al pastor carved off a trompo, birria, and Mariscos Jalisco's fried shrimp taco. $3 each. Do this at least four times.
The San Gabriel Valley. Monterey Park, Alhambra, San Gabriel — the best Chinese food in North America, full stop. Sichuan, Shanghainese, Taiwanese, hand-pulled noodles, dim sum. Worth the 30-minute drive from Downtown; most visitors never go and it's the biggest thing they miss.
Koreatown. Enormous, 24-hour, and the best value in the city. KBBQ, then a bar, then more food at 02:00.
Oaxacan. Guelaguetza for mole. There's nothing like it in SF.
Grand Central Market (DTLA) — a hundred-year-old food hall; go for the tacos and the eggs, skip the queues with lines around the block.
Langer's — a pastrami sandwich that is genuinely argued to beat New York's. Near MacArthur Park; drive, park in their lot.
Book-ahead dinners — Bestia and Bavel (Arts District) are the two everyone wants; reserve three to four weeks out or eat at the bar.
Smorgasburg LA — Sundays, Downtown, a hundred vendors. The single best food afternoon in the city.

§18

LA: Must See

Tiers, then a day and a night

LA's must-sees are worse than SF's at the famous end and far better at the strange end. The Walk of Fame is genuinely the most disappointing famous street in America; the Museum of Jurassic Technology is one of the most interesting rooms on earth. Weight your week accordingly.

Tier 1 — the non-negotiables

#	Thing	Time	Cost	When & why
1	Tacos from a truck	20 min	$12	Do this four times, not once. Al pastor carved off a trompo, birria, and Mariscos Jalisco's fried shrimp taco in Boyle Heights. A strip mall or a parking lot will beat almost every restaurant meal you eat all year, for $3 a taco.
2	PCH to Malibu	3h	Gas	Late morning, top down if you have one. One of the great drives on earth, forty minutes from Santa Monica. Stop at El Matador — sea stacks, caves, near-empty on a weekday.
3	The Getty Center	3h	Parking only	Free entry; you pay to park. A tram up the hill to Richard Meier travertine, gardens, and a view across the whole basin to the ocean. The best two hours of culture in LA and it isn't close.
4	Morning hike	1.5h	Free	07:00–08:30. Runyon Canyon for the crowd and the city-watching, Griffith for the longer trail and the observatory. This is a normal business-meeting format here — accept every invitation to one.
5	The San Gabriel Valley	3h	$25	Monterey Park, Alhambra, San Gabriel. The best Chinese food in North America, thirty minutes east of Downtown, and almost no visitor goes. This is the single biggest thing people miss in LA.
6	Koreatown at midnight	3h	$45	KBBQ, then a bar, then more food at 02:00. The only part of LA genuinely awake at 03:00, and the best value in the county.
7	Griffith Observatory at dusk	2h	Free	Arrive an hour before sunset. Free entry, free telescopes after dark, and the whole basin lighting up beneath you.
8	Venice → Santa Monica by bike	2h	$15	Late afternoon on the beach path. Muscle Beach, the skate park, the drum circles, then the pier. Deeply touristy and completely worth it once.
9	Grand Central Market	1h	$20	A hundred-year-old Downtown food hall. Go for the tacos and the eggs; skip anything with a line around the block.
10	Smorgasburg LA	3h	$35	Sundays only, Downtown, a hundred vendors. If your week contains a Sunday, this is what it's for.

Tier 3 — the only-in-LA oddities

LA rewards the strange far more than the famous. All of these are free or nearly so, and none are on a tour route.

CULVER CITY

Museum of Jurassic Technology. The strangest museum in America. Dim rooms of exhibits that deliberately blur the real, the invented and the unverifiable, presented with total sincerity. You leave genuinely unsure what you just saw. Go alone, allow two hours.

VENICE

The Venice Canals. Actual canals with footbridges and ducks, two blocks inland from the boardwalk chaos. Silent, residential, and almost nobody walks over from the beach to find them.

WATTS

Watts Towers. Seventeen interlocking sculptures built by one Italian immigrant, alone, by hand, from scrap steel and broken tile, over thirty-three years. The city tried to demolish them and failed a stress test trying.

DTLA

The Bradbury Building. An 1893 office building with a five-storey light-filled atrium of wrought iron and open-cage lifts. Blade Runner's final act. The lobby is free to walk into.

DTLA

Angels Flight. A 1901 funicular railway that climbs 298 feet up Bunker Hill. One dollar, under a minute, and the most charming pointless thing in the city.

HOLLYWOOD

Hollywood Forever Cemetery. Summer film screenings projected onto a mausoleum wall while a few thousand people picnic between the graves. Also Day of the Dead, at full scale.

GRIFFITH PARK

Bronson Caves. A five-minute walk off the road to the Batcave entrance from the 1960s series, plus a century of westerns and sci-fi. Free, unmarked, anticlimactic in the best way.

BALDWIN HILLS

Scenic Overlook. 282 stairs straight up for the clearest, least touristed view of the entire basin — ocean to downtown to the mountains on one turn.

The day — ocean to hills

07:00Runyon Canyon or GriffithThe city's morning ritual. Runyon for people-watching and the Hollywood crowd, Griffith for the longer trail and the observatory at the top. Take a meeting on it — that's what it's for.

09:00Coffee, Silver Lake or VenicePatio, outside, phone down. Everything social in LA happens outdoors.

10:30Drive PCH to MalibuThe Pacific Coast Highway north out of Santa Monica is one of the great drives on earth and it's forty minutes from where you're staying. Stop at El Matador beach — sea stacks, caves, almost empty on a weekday.

13:00Tacos, somewhere unglamorousA truck, a strip mall, a parking lot. This will be better than most restaurant meals you eat all year.

14:30The Getty CenterFree entry (you pay to park), a tram up the hill, Richard Meier travertine, and a view over the whole basin to the ocean. The best two hours of culture in LA.

17:00Venice → Santa Monica on the boardwalkRent a bike. Muscle Beach, the skate park, the drum circles, then the pier. Deeply touristy and completely worth it once.

19:00Sunset from El Matador, Point Dume, or the pierLA sunsets over the Pacific are the thing people move here for.

20:30Koreatown for dinnerKBBQ, late, loud, cheap. The night starts here.

The night

Silver Lake / Echo Park — the good bars, walkable, no dress code, actual conversation. Start here.
Live music — The Echo and Echoplex (Echo Park), Zebulon (Frogtown, the best room in LA), Gold Diggers (Hollywood, a bar with a studio and a hotel attached), the Troubadour and the Roxy for the historic rooms.
DTLA warehouses — the techno and house layer, unlisted, Instagram-and-group-chat driven, and much larger than SF's.
Koreatown — the only part of LA that's genuinely awake at 03:00. Norebang (karaoke rooms), soju, and food all night.
Skip Hollywood bottle-service clubs unless someone else is paying, and skip anything with a promoter texting you.
Last call is 02:00, same as SF. Getting home is the difference: budget $30–60 for a late Uber across town, and don't drive after drinking — LA enforcement is heavy and the distances are long.

§19

Operating Data

Money, safety, vocabulary

Costs, both cities

Item	SF	LA
Coffee	$5–7	$5–8
Taco / burrito lunch	$14–18	$3–12
Mid-range dinner	$45–75	$40–70
Cocktail	$17–22	$16–20
Crosstown ride	$18–32	$25–60
Hostel / coliving bed	$50–80	$45–90
Car rental / day	Don't	$45–80

The +30% rule

The menu price is not the price. Sales tax is added at the register (8.625% SF, 9.5% LA), tipping is 18–20% and the terminal suggests 25%, and many SF restaurants add a further 4–5% city-mandate surcharge. Assume every posted price is 30% low.

Practical

Payment: card and Apple Pay everywhere. Keep $40 cash for Zeitgeist, Swan Oyster Depot, taco trucks and Chinatown takeaway.
Weed: legal at 21+ in California, dispensaries everywhere, not legal to smoke in public.
Earthquakes: a non-issue for a short trip. If one happens: away from windows, stay inside, don't run downstairs.
Clothing: SF needs layers and a windproof shell. LA needs sunglasses and one warm thing for the evening. Pack for both; they are not the same climate.
Route around after dark: in SF the Tenderloin (Market–Van Ness–Geary–Mason), 6th St, Civic Center. In LA, Skid Row (east of Main, DTLA), parts of MacArthur Park, and the Venice boardwalk after dark.
Cars in LA: the same bipping rule applies — nothing visible, ever, including in a hotel garage.

Vocabulary

Term	Means
The City	San Francisco, only. Never "San Fran," never "Frisco."
Karl	The SF fog. It has a name and a following.
Cerebral Valley	Hayes Valley as the AI scene's home turf.
Bipping	Breaking into a parked car.
The Wiggle	A zig-zag bike route from Market to Golden Gate Park avoiding every hill.
The Gundo	El Segundo, as the LA hard-tech scene.
The Westside	LA west of La Cienega — Santa Monica, Venice, Brentwood. "The Eastside" is Silver Lake, Echo Park, Highland Park.
The 405 / the 10	LA freeways take a definite article. Saying "405" without "the" is the LA equivalent of "Frisco."
SGV	San Gabriel Valley — east of Downtown, the Chinese food.
