Shinpachi Shokudo Shinjuku Tonanguchi is a Japanese home-style restaurant near the east exit of Shinjuku Station that serves charcoal-grilled fish set meals from the morning. The salmon, mackerel, and salmon belly grill sets come with rice and miso soup, while side dishes such as natto or minced tuna hoe are ordered separately. Each seat has a tablet for ordering in Korean, and after the meal you scan the QR number ticket at your seat at the kiosk to pay. The morning set's fish is small, so the portion is light relative to the rice.
