"When: Tuesday-Friday, 3-5pm The neighborhood seafood market in Noe Valley doubles as a casual, counter-service restaurant, and one that can fulfill any late afternoon desire for shellfish or fantastic clam chowder. Every Tuesday through Friday from 3-5pm, oysters by the half dozen and glasses of cava are half off, which is as good an excuse as any to block off an "appointment" on your calendar and get here for a late-day snack." - julia chen 1, lani conway, ricky rodriguez
