On May 1, Japan will celebrate the beginning of the Reiwa era and the Enthronement of Emperor Naruhito. The Oak Door restaurant inside the Grand Hyatt Tokyo is doing so with a special burger. Dubbed the Golden Giant Burger, it consists of a 1kg beef patty, lettuce, tomatoes, onions, cheddar cheese, Wagyu beef slices, foie gras, and freshly shaved black truffles. It's served atop gold-dusted buns alongside triple-cooked giant fried potatoes and a magnum-sized bottle of champagne, red, or white wine. For smaller appetites, there's a Golden "R" version, which keeps the gold-dusted bun, foie gras, Wagyu slices, and black truffles while adding Madera Sauce and goat cheese. The Golden Giant will be served through June 30, and orders must be placed at least three days in advance.
