For those who really want to see the wilder side of gay clubs in San Francisco, head to Aunt Charlie's Lounge in the Tenderloin. Visitors who are unfamiliar with the area should be aware that the Tenderloin neighborhood has a reputation as the toughest neighborhood in town, so use your head and act accordingly. Once you're in Aunt Charlie's, though, you'll be treated to some genuine warmth and one of the best drag shows in all of the Bay Area. This is not a dress up and get fancy place; the beers are in cans and the snacks are mostly on the floor. But it's a great time for those who know how to loosen up.
