This is without a doubt the most popular gay bar in Philadelphia, drawing huge crowds every night that I have visited. While there is a dance floor, the place seems much more like a large friendly bar than a dance club. This suits me fine as I enjoying talking with people and drinking more than cutting up the rug, but friends of mine from New York were a little surprised by the atmosphere and feel of "the club" Woody's.
This would be a great place to go if you're just coming out, as so many of the patrons are ridiculously young. I didn't feel out of place as many other guys were in their late 20's, but Woody's is definitely the most consistently young bar I've been to. Perhaps that helps explain its ongoing popularity!
Food is served downstairs, and there is a video bar upstairs housed in a separate room from the dance floor area. Lots of room for circulating and attempting to make eye contact with the man of your dreams.
