This counter-seating-only seafood establishment is a longtime, family-owned restaurant and market (since 1912) on Polk Street in the Russian Hill district. The menu on the wall tempts patrons with clam chowder, shucked oysters, and a variety of other seafood options. The friendly brothers will serve you at the marble counter (with 20 stools), or you can order your food to go. San Francisco memorabilia, fish and crab posters, and a rubber ducky collection complete the setting. If you want to eat dinner here, go early: the restaurant closes at 5:30 pm.
