The Forbes Traveler has an article on America's most expensive burgers. It features the Wall Street Burger Shoppe burger that Adam mentioned earlier this week as well as the famous short rib–truffle-stuffed creation by Daniel Boulud. But most outrageous, and by a mile, is the $5,000 burger from Fleur de Lys in Las Vegas. And I thought the Kobe burger at the Old Homestead Steakhouse, which is no longer available and which sold for $81, was expensive. So burger lovers, what's the most you have ever paid for a burger? Was it worth it?
