Feeling flush? Then Chef Hubert Keller has just the burger waiting for you at the Fleur restaurant in Mandalay Bay, Las Vegas. And it will only set you back $5,000.
It is Kobe beef topped with foie gras and black truffle on a brioche truffle bun with truffle sauce. The recommended accompaniment is a bottle of Chateau Petrus 1995, on the wine list at $5,300.
