Last week I told you about the world's most expensive burger created by Serendipity 3 - truffle-infused, fried quail egg, blini, creme fraiche, Kaluga caviar, and Campagna roll burger. It seems that this week, another burger, Douche Burger, which includes Kobe beef patty (wrapped in gold leaf), foie gras, caviar, lobster, truffles, imported aged gruyere cheese (melted with champagne steam) kopi luwak bbq sauce and Himalayan rock salt. This burger costs $666. Imagine! Douche Burger is now the most expensive burger.
I also read this nice article on ABC News on the TOP Five most expensive burgers.
