Boudin Sourdough Bakery and Cafe is located on Jefferson and Taylor, but there are also locations in the wharf area at Pier 39 and Ghirardelli Square. They have been making the original San Francisco sourdough bread since 1849 and it is like no bread you'll ever have anywhere else in the world.
If you want a light lunch, you can get a bread bowl filled with creamy clam chowder to die for. No trip to San Francisco would be complete for us without taking several loaves of San Francisco sourdough bread home with us. Even if we're just passing through the San Francisco Airport, we always buy bread to take home.
Not to be missed while strolling the wharf are foods to eat on the go: small clam chowders in bread bowls, seafood cocktails served in paper trays, fresh crab legs, Italian (Scomas and Aliotos) and Chinese restaurants representing the city's founding heritages, and of course some of the best chocolate and hot fudge sundaes to be found at Ghirardelli Square.
You can eat your way down the wharf while watching the functioning fish markets in operation. It's amazing to watch how quickly they can shuck the seafoods from their shells. Then before leaving purchase some fresh seafood, fin fish, crabs, clams, salmon, and others, to cook at home.
