San Francisco has a genuine fishing fleet, one of the best crab seasons on the west coast, and a waterfront that sells seafood at some of the highest prices in the country. Those facts sit uncomfortably together. Searching cheap seafood near me here produces mostly the wrong end of Fisherman's Wharf, which is where the fewest locals eat. The cheap version exists in three specific places, and none of them are on the postcard.
Cheap seafood in this city is a timing and geography question: the same oyster costs half as much three hours earlier and a mile away. Tell Karpo when you want to eat and where you are, and it will point you at the version that is actually good value.
Happy hour is the real answer
The single largest price difference in San Francisco seafood is time of day, not location. Oyster happy hours across the city routinely run at a fraction of the evening price, generally in a window in the late afternoon on weekdays, and they use the same oysters from the same growers as the dinner service. A dozen at happy hour with a glass of something cold is one of the best cheap meals the city offers.
Two caveats worth knowing. The discounted oyster is usually one specific variety rather than the whole list, and the deal frequently applies only at the bar rather than at a table. Both are fine if you know before you sit down and irritating if you discover them on the bill.

Chinatown and the Sunset: fish sold as food, not as an experience
The cheapest seafood in San Francisco is sold in Chinatown along Stockton Street and in the Sunset and Richmond fish markets, where whole fish, live crab, prawns and clams are priced for people cooking dinner rather than for visitors. Many of these shops will clean and cut whatever you buy at no charge, which turns a modest amount of money into a serious meal at home.
The restaurants behind those markets follow the same economics. Cantonese seafood houses in the outer avenues will do a steamed whole fish or salt-and-pepper crab for a fraction of what the same dish costs downtown, and they cook it better because it is the thing they do every day. This is the best value seafood dinner in the city and it is almost never on a list.
Crab season and what it actually means
Dungeness crab is the local season worth planning around. The recreational and commercial fisheries typically open in the late autumn and run into spring, with delays in some years because of whale entanglement risk or domoic acid testing, and the opening date moves. When the season is open and landings are strong, whole cooked crab from a market is dramatically cheaper than crab in a restaurant and takes ten minutes to deal with at home.
If you want to catch your own, the pier fishing along the bay does not require a licence from public piers in California, which makes it one of the few genuinely free food activities in the city. Crab and fish taken this way are subject to size and season rules, and the health advisories about which species to limit in bay waters are worth reading before you eat what you catch.
The fry shack tradition
The third cheap category is fried: fish and chips at the older waterfront counters, the Vietnamese and Filipino kitchens doing fried fish plates, and the Mexican seafood spots in the Mission doing tostadas, ceviche and fried fish tacos. Baja-style seafood in this city is consistently underpriced relative to how good it is, and a couple of fish tacos and an agua fresca lands well under the price of a sandwich downtown.
Avoid the stretch of the wharf where the prices are on a board facing a cruise terminal. Walk east toward the working piers or south into the Mission and the same money buys twice the food. The one wharf item that remains genuinely good value is the walk-away crab cocktail from a sidewalk cart in season, which is a legitimate San Francisco thing to eat.
Buying well when it is cheap
A few questions make cheap seafood reliably good. Ask what came in that morning rather than what is on the list. Buy whole rather than filleted where you can, since it is cheaper and keeps better. Look at the eyes and the gills on a whole fish, and at whether the shellfish are closed and heavy. And when you are choosing between species, the Seafood Watch guidance is a genuinely useful, free tool for both sustainability and, indirectly, price — abundant species are cheap species.
Finally, eat what is landing rather than what you planned to eat. The best cheap seafood meal in San Francisco is always the thing that came in in quantity that week, and the shop will tell you what that is if you ask.

Ask Karpo first
Happy hour windows, crab season openings and what landed this morning all change week to week, and they decide whether this meal is cheap or not. Ask Karpo which oyster hours are running near you today, whether crab season is open, and which markets are worth the trip — it answers in iMessage, in a sentence.
