Went here with a group of friends in November. One of the friends got some hookup so we didn't pay to get in and VIP line pass. So couldn't complain about paying a cover charge or waiting forever in a line. The club itself is pretty huge. We surveyed about 3 floors. The look was pretty cool throughout. The house DJ list is impressive too. Tiesto, Calvin Harris, Steve Aoki & Deadmau5. Each floor having its own decor, theme & DJs. Two serious downsides were that it was packed like a sardine can in there. Also the stairs are KILLER. There's only a few elevators so the main route of travel inside the club is taking flights of stairs. I can imagine it's even more a nightmare when one is drunk & wearing high heels. Frankly I'm shocked no ones gotten seriously hurt and/or sued Hakkasan for dangerous conditions.
One person is our group did lose her purse. When she called the next day, fortunately they had it at the club intact. Apparently she had left it at one of the bars after ordering some drinks & the bartender saw it and turned it in.
Like all clubs on the strip. It's no fun if you're not on the list and pay full price after waiting in a line for hours. Always a good idea to get some type of hookup or deal thru a club host or casino or such.
