Japan's fast food culture puts a unique twist on an original burger. McDonald's in Japan has recently unveiled their recent additions to their repetoire--a macaroni, shrimp and white sauce burger covered in bread crumbs.

Kotaku.com reported that the burgers are called "Gracoro Burgers" which is a combination of Japanse "Korokke," and "gratin." Gratin is a popular dish in Japan made from noodles, creamy sauce and shrimp baked in the oven, often with cheese creating a creamy concoction of gooey goodness, while Korokke is a Japanese version of the croquette, usually with potato inside and a breaded crumb outside.

Apparenlty McDonalds has been offering up the burger on their menu since 1993 but it's only on their winter menu. Kokatu.com said, "Gracoro Burger has been offered only during the winter months, and because of that, it is pretty much the equivalent of the McRib in that there is a lot of burger fandom surrounding the Gracoro. Burger fans get excited about it in the same way that Americans get jazzed when the McRib goes back on sale."

Other creative concoctions in Japanese fast food restaurants includes Burger King's "Premium Kuro Burger," which features a black burger that is colored with bamboo charcoal mixed into the dough. The ketchup is black and flavored with squid ink.

In Japanese, "kuro" literally means black and was available for a limited time starting Sept. 28 in commemoration of Burger King's five year anniversary in Japan.

"kuro" literally means black and now for 790 yen hungry patrons can purchase the burger with a drink and fries for a limited time. The burger will debut on Sept. 28 in commemoration of its five year anniversary in Japan.

Other interesting Japanese fast food creations include KFC's savory salt Ginger Chicken potato chips, and a pumpkin burger from Burger King, reports The Huffington Post.
