Whole lotta haters on here. I can only assume that they don't hit the high end clubs in Vegas very often.
If you're planning on hitting this club, all the standard rules apply. They will pack it wall-to-wall. Their goal is to get you to buy a table. If you're a guy, look good, and have lots of pretty little things hanging around you. This is not the place to go if you're a group of nine and don't buy a table.
Let me be clear here: It doesn't matter who you know, or what list you're on. The only thing that matters is the money you are willing to spend. The more money you spend, the better the experience. Ever notice how the non-guestlist people get in first? That's because they're paying. Notice how the people buying the high end drinks get served first? Or how the people buying tables get their own dance space and service? That's right....MONEY.
Just. Like. Every. Other. Club. On. The. Strip.
I went last weekend with my wife and other couple; we had a great time. Yes, the common dance areas were packed, what did you expect? For the most part everyone was friendly; we met several other couples / groups and had a blast. Heck, we even befriended two of the bartenders who hooked us up with drinks and laughs.
If you've been to Tao on a Friday or Sat night, this place is less packed and better designed. Better vibe too. Surrender at Encore is hella bigger, but mostly outdoors. Same with Pure at Caesers.
TL;DR - It's a good Vegas club. Ignore the trolls.
