There are a few options when it comes to bars on top of buildings in Las Vegas. Mix is one of them on the top floor of THEhotel.
Would I spend all night here, dancing away with many cocktails? No
This is a one cocktail place.
However, this one cocktail place is so great for after a dinner at Mandalay bay or somewhere near by. I brought my parents and some friends up here for a look at the view and we had a great time looking out over the city. It is expensive, and your paying for the view, but get there before 10 and take care of one of the hosts and sit outside right at the edge for an hour and relax, you wont be disappointed!!
