There's the "Hot Gold Masala" burger which towers with a Big Mac-style club bun, but oddly enough, only contains one battered and deep-fried chicken filet between the middle and the heel. Between the crown and middle bun, there's only tomato, lettuce, onion, and spicy curry sauce. There's also a slice of American cheese in there.
The burger are part of a larger "World of McDonald's" promo in Japan, showcasing limited-time menu items that represent flavors from different cuisines/cultures around the world. Last month, they had a French theme and up next is an Australian theme with an Aussie Deli burger to come in late August.
