This aggressively nautical North Beach seafood sanctuary is a San Francisco institution, with some of the best chowder-filled bread bowls in a city full of them, $1.50 oyster specials on Mondays and Saturdays. The wait can be long and the waitstaff can be salty (but in a charming "we've been doing this a while" kind of way), but once you have a bite of velvety, bacon-y, clam chowder you won't be thinking about anything else.
