New York City’s Wall Street Burger Shoppe has the honor of selling the world’s most expensive hamburger. The Richard Nouveau burger is 10 ounces of Prime Kobe beef topped with 25 grams of black truffles, seared foie gras, aged Gruyere cheese and edible (yes, edible) gold flakes. The RN burger is topped with a homemade “golden truffle” mayonnaise that includes both gold flakes and black truffles. Hmm… do you get fries with that?

Cost: $175.00
