I am not from SF, so I am unfamiliar with the best restaurants up there, but I am planning a birthday party for my boyfriend, whose pet peeve is overpaying for food. he's a foodie...he usually spends an hour perusing this board (hope he doesn't see this post!) before we go out anywhere. the food needs to be excellent, the space needs to hold 20ish people, and it can't be too pricey. any recos?
