Chef Hubert Keller's Fleur has two dining spaces, one fairly intimate and one open to Mandalay Bay's restaurant row, so you can watch the world (or at least Las Vegas) go by. Small plates themed to the USA, China, Thailand, Spain, and France are served along with burgers and steaks. Menu items are seasonal, but signatures include "In the Shower" mac and cheese with lobster and shrimp, kushi oysters on green curry shaved ice, and a French onion tarte flambé. Then there's the Fleur Burger 5000, a Wagyu beef hamburger with foie gras, truffles, and a bottle of 1995 Chateau Petrus, costing—you guessed it—$5,000. Console yourself with pineapple carpaccio, or a brownie lollipop.
