The chef of Aqua (Michael Mina) is no longer involved with that restaurant. He has/or is about-to-open another restaurant in Las Vegas.
My favorite restaurant in Las Vegas is Jasmine at the Bellagio. Great food and service and a dynamite view of the fountains. Be sure to ask for a window table. I have had great Cantonese food all over the world; Having said that, I am still very impressed with Jasmine
