Industry Kitchen, a restaurant located at New York City’s South Street Seaport, holds the Guinness World Record for offering the world’s most expensive pizza. The pizza, which you have to order two days in advance, is topped with 24 karat gold leaves, Stilton blue cheese, Hudson Valley foie gras, Platinum Osetra caviar, French Périgord truffle and Almas caviar, which is optional for an extra $700.
(I'll stick with my pepperoni & cheese Pizza thanks.)
