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 United States, France, Spain, Peru, and Greece are served along with burgers and steaks. Menu items are seasonal, but signatures include white onion soup veloute with truffle oil, and grilled octopus with patatas bravas. Then there's the Fleur Burger 5000, a Wagyu beef hamburger with foie gras, truffles, and a bottle of 1996 Chateau Petrus, costing—you guessed it—$5,000. Console yourself with vanilla crème brûlée or a brownie lollipop. Or try the Michael Jackson One menu, a preshow prix-fixe for $49 per person.
