I have been to this lounge a couple of times this past year. Once to see a live dub-step show and once again to hang with family and friends.
Upon entering after the elevator ride up you walk through dimly lit halls to get to each room of the floor. It's decorated beautifully in rich wood and classy dark structures. There definitely is great ambiance.
The best part I must say along with other critics is the view! It is an absolutely stunning view of the city. Great place to relax and have a drink. We had free drink coupons, but obviously the drinks aren't the best deals you'd get in town.
The vibe was totally different when I had came here for the dub-step show. Obviously there was a different crowd and the room was a bit small to be having such loud bass playing all night. Other than that, the couches are luscious and the workers I had come across weren't all that bad, but could be a little friendlier in my opinion.
Overall, great lounge to check out.
