What IS "Genghis Khan" cooking in Japan? In other series it gets casually passed off as a kind of yakiniku kind of restaurant, where the meat gets cooked over a mesh grill and an open flame. In other series, it's another way of referencing Korean BBQ restaurants, where the grill is a metal plate with "vents" to drain off the excess fat, heated over a gas flame. In that Hokkaido Gyaru series, it's something else entirely, and here the translators claim it's Mongolian BBQ!!
