My girlfriend and I happened to go here after receiving some VIP passes with 2 for 1 cocktail drinks from a friend. It's located on the 2nd floor of the Aria hotel. We arrived just after 10pm and there was a short line waiting to get in. The wait wasn't long. I paid $10 for my girlfriend, while I was charged $20. We didn't figure out that we could of got in for free until AFTER we left and looked at our VIP passes. We were both given 3 free drink cards each for a total of 6, which we were told that it's open bar from 10pm to midnight. Sounds like a great deal even after paying $30!!! The bartender told us that if we use all of our drink coupons before midnight, we can get more from the staff at the door/curtain at the entrance. It seemed that people were definitely taking advantage of it because the more the night went on, the more people seemed that not know how to dance. :)
We used all 6 of our coupons and our drinks were made pretty strong. There was a DJ spinning top 40 music, but ended playing more R&B/Hip-Hop after about 30 mins, which got more people dancing. It was a good crowd, but wasn't packed like sardines. It seemed that people started clearing out to venture out to different clubs as midnight approached.
This is a great spot to start your night out on the town. I will definitely come back, especially during the open bar hours.
