Once you actually figure out how to get here it is a very nice bar. It feels like a hidden little spot in the stratosphere, but it's actually kinda the same area you go to when you want to get to the top. I went here for the Yelp Drinks promo. Met up with some cool Yelpers and had a couple of Chocolate Martinis. They were pretty awesome. It's all alcohol and they are a decent size, so you can get a pretty nice buzz going after two, back to back. It was sweet and at first a little too overpowering but your taste buds kinda just adjust to it and then you can enjoy the ride.
The ambiance is great. You have the beautiful view of practically the entire Vegas valley, which you should be use to if you go up to the top for any of the rides, or even just go up there to take in the sights. The chairs are comfy, and the lighting is just low enough. The server was friendly. It's a pretty classy and tasteful bar.
There are also half priced appetizers from 4-7 along with 2-for-1 Martinis.
Will definitely come back here.
