The $5,000 "Fleur Burger 5000"

Some time ago, I had heard what sounded like a  bogus rumor about a $5,000 burger that was put on the regular menu of a restaurant somewhere; & that it shattered the previous record for world's most expensive burger.  That distinction, if you care to know, was held by the £95 (or roughly $150) burger introduced by a Burger King in the UK back in 2008.  But a $5,000 burger!?  I mean, is it possible that there is a chef out there with the audacity to put something like this on their menu - and more importantly, are there people who are crazy enough to buy it?  Well....yes, and yes.  French chef Hubert Keller features the $5,000 Fleur Burger 5000 on the dinner menu of his Las Vegas restaurant, Fleur (located in the Mandalay Bay Casino). What goes into a $5K burger, you ask?  The Fleur Burger 5000 is made with a hearty slab of a Wagyu Kobe beef patty that's topped with an equally impressive slice of foie gras and black truffle shavings.  All of it is carefully held together with a brioche truffle bun and drizzled with a rich truffle sauce. Your Fleur Burger, should you be rich (or drunk) enough to actually order one, comes with a bottle of 1990 Chateau Petrus.  Turns out, the '90 will run you $3,000.  So the burger itself is actually only about $2,000.  Though it's not clear whether Keller allows patrons to order the burger without the bottle.  I guess I'll never know....
