If you find yourself in San Francisco on a Thursday evening and are looking for something different, call some friends and swing by the California Academy of Sciences for an evening of "music, creatures and cocktails". Every week on Thursdays they feature live bands or DJs and various events- meanwhile cocktail bars stand ready for your serving all throughout the museum. With drink in hand, Cruise through various exhibits, hang with the butterflies in the biodome or wander downstairs and gaze at all of the glorious sea creatures who appear to be swimming to the DJ's beats. $12 gets you in and if you get there early you can snag free tickets to the planetarium show.
