Sukiya Namba Rakuza

Sukiya is a 24-hour Japanese chain near Namba Station serving gyudon and set meals. The menu includes gyudon, sukiyaki, and natto set meals, plus a gyudon light version that replaces rice with tofu and vegetables. Orders can be placed at kiosks or table tablets in Korean, English, or Chinese, and food comes out quickly. The menu centers on simple single meals, so it is not a restaurant to seek out specifically in Osaka.
