My oldest turned 21. (mind trip for me, too) She's bringing college friends from out-of-state to San Francisco and I would like her to give them a friendly taste of what we consider unique. Of course, she's interested in bars/lounges... where would you let your 21 daughter go? And I'm looking for any hip places that I would be out of place going to, but would be safe for her and her young friends. And, of course, they have student budgets. Thanks in advance.
