I'll tread lightly on this one since my girlfriend loves this place.
So here's the deal. After the Coyotes game, we stopped in for a drink and to relax for a bit before leaving to head home. I found the atmosphere to be a bit different. not bad, just a little different than what I am used to.
The dueling pianos had just stared and there were some older women there who were already way too drunk, trying to dance on stage. That was interesting to watch. One of the piano players even took one of the gals off the stage at some point.
The atmosphere isn't bad. Once the place filled up, the songs started and the crowd was expected to sing along to them. Some of the songs are quite explicit, so this may not suit everyone's taste.
I also felt embarrassed for the women who the piano players called up to sing in front of everyone. They were good sports about it though. The service was ok, nothing too amazing. The place was super loud though, so conversation here is pretty much out of the question.
I would go back only if I was brought back by my girlfriend. Not sure I would go on my own.
