Vegas chef Hubert Keller is serving one fat burger at his Fleur restaurant at the Mandalay Bay resort for $5,000.
Keller's Kobe beef burger is topped with foie gras, black truffle, and truffle sauce and is served on a brioche truffle bun.
The kicker is that Keller throws in a bottle of Chateau Petrus 1995 – which retails for about $5,000.
