You MUST go...
Rose.Rabbit.Lie is a restaurant. Vegas Nocturne is a show with two performances. But over the evening the one kind of blends into the other and where you eat dramatically affects how much 'show' is in your dinner theatre. There are quiet rooms that focus on the food, medium rooms that offer a mix, and a noisily packed bar/dining room in which enjoying one's dinner would be nearly impossible. When making your reservation (speaking with your hostess?) you should let them know what you want.
That said, the food itself is inventive and for the most part utterly delicious. Almost everything comes in small plates so you'll have a chance to sample many dishes though the prices are aggressive. BTW, the mixed drinks are spectacular.
