Had my birthday here last month, it was my first time here and I'm a fan!
The guest list process was very easy, and when I had any questions they were answered almost immediately by email.
My guests all got in for free as promised, and there was a pretty good crowd when we arrived (just before 11pm). The multiple bars are great, we never had to wait more than 2 minutes for a drink! Lots of drink specials on weekends.
One negative is the venue is quite small, it actually doesn't seem that small once you're on the dance floor, Still lots of room to dance with your friends. And the music was some good fun top 40, which I always enjoy :)
