I often come here on Thursdays, when they have college nights. Make sure to bring cash for the entry fee- it's $5 and then another dollar if you want to check a coat. Make sure you bring cash.
My experience has been slightly touch and go- the bouncers don't really seem to pay attention to the dance area, which is an issue, because there's almost always some creepy, stalkerish straight guy milling around and getting far too familiar with the girls. Seriously, it's a gay bar! The girls there are not attracted to men and/or are there specifically because they don't want guys to hit on them. I went there one night with a group of my girlfriends and we were legitimately scared of one guy who wouldn't leave us alone. Pay attention to the dance floor, please!
That being said, I usually have a really great time. The music is fun and the DJs keep the energy up. I'm glad that the only smoking area is outside so I don't have to breathe in smoke while I'm dancing. I have also been there a few times when the Pittsburgh AIDS Task Force was there doing free HIV/AIDS testing, which I think is so important.
