Sukiya serves gyudon and a morning set meal of grilled fish around Sapporo Grand Hotel. Besides gyudon, the morning set includes white rice, mackerel, and warm soup. The shop is open almost 24 hours, so you can stop by early in the morning or late at night. You order on a tablet at your seat or at a Korean-language kiosk, receive your food and receipt, then pay at the counter after the meal.
