Yakiton Daio Ikebukuro is an izakaya in Ikebukuro that serves yakiniku, gopchang (grilled intestines), and drinks. It grills beef tongue, assorted cuts, and wagyu, and also takes orders for tomato sour and kiwi sour. A Korean-speaking staff member is on hand, and the all-you-can-drink option runs for 90 minutes. The space is small and tightly packed, like a typical Japanese shop.
