That's it. That's Aria. The anchor of CityCenter. Impressed? Can't say that I was. However, I will reserve judgement until I can get back over there to experience it again, and see how it compares to the grand-opening hubbub.
In any case let's hope this 8 billion dollar gamble called CityCenter pays off.
