With an improbable mountainous cabin vibe, Cafe Flore is a long-time Castro chill/hot spot with both (heated) outdoor and indoor seating.
A full menu and bar compliment the cafe offerings, with food service replaced by live DJ's Thursday through Saturday nights after 10pm, with a full schedule of events.
