Rotomatagi is a Japanese izakaya near Shinjuku Station and Seibu-Shinjuku Station in Kabukicho, Tokyo. It serves robatayaki and genshiyaki grilled over charcoal, along with fish dishes, thick beef tongue, pot rice, and gibier such as deer and lamb, plus a range of Japanese alcohol. Private rooms are available for groups. Cooking takes time, so food arrives slowly.
