Big
Whoever said size matters, obviously has not patronized Big, a postage-stamp size space making hugely inventive cocktails. Defying any good business sense, it’s open or closed at any time, on any day, for any reason, says the website. And, without a menu, the expert mixologists whip up cocktails based on your mood and your spirit preferences, Big is as unconventional and whimsical as any San Francisco experience you’ll encounter, making it that perfect date-slash-adventure you’ll be talking about for a long time.
761 Post Street (between Leavenworth and Jones streets); no phone.
