If you're questioning whether to go about this restaurant, just do it. It'll be pricy, but you won't regret it. The service, food, and ambiance are incomparable and allow you to feel as if you're in Las Vegas from a distance (so you don't have to cringe at the disgustingly drunk party-goers walking on the strip).
If you sit on the patio, you get front row seats to the synchronized fountain shows, which is actually a lot more magical than I originally thought it'd be. It's really something special.
The food was great - it was the first time I actually liked foie gras, as the course on the Degustation Menu was to die for. Everything, from start to finish, felt delicate and thoughtful and I couldn't imagine dining my first night in Vegas anywhere else.
