Le Burger Extravagant

What does it take to make the world’s most expensive burger? Japanese waygu beef, infused with 10-herb white truffle butter, seasoned with Alderwood smoked pacific sea salt, topped with cheddar cheese, shaved black truffles and a fried quail egg served on a white truffle-buttered Campagna roll and finished with a blini, crème fraiche and Kaluga golden caviar. Oh -- and, a solid gold diamond-encrusted toothpick on the side. The damage? $293, by appointment only, also at the world-famously pricey Serendipity 3 in New York. (Liz Steger)
