Yoshinoya / Sukiya Gyudon

Yoshinoya and Sukiya are Japan’s two largest gyudon (beef on rice) chains, serving bowls of simmered beef and onions over steamed rice for 400-600 JPY per bowl—the fastest, cheapest, and most satisfying quick family meal, and a legitimate cultural food experience. Both chains offer set meals with miso soup and salad for under 600 JPY and are open 24 hours at most Tokyo locations. TripAdvisor Japan food guides regularly feature gyudon chains as essential eating for budget-conscious families, with children consistently enjoying the sweet-savoury beef flavour and the ritual of sprinkling red ginger (beni shoga) on top.
