As is everything in Vegas, the FleurBurger 5000 is over the top with a hefty price tag of $5,000.00. Created by Chef Hubert Keller, the FleurBurger 5000 is served at Fleur de Lys in Mandalay Bay. It is a Kobe burger containing foie gras, a special truffle sauce, and is served on a brioche truffle bun with black truffles on the side. The burger is served with a bottle of Chateau Petrus 1990 poured in Ichendorf Brunello stemware (you get to keep the stemware)imported from Italy, and a certificate of authenticity will be mailed to your home so you can brag to your friends about how you spent $5000 in Vegas...on a burger.
