Katsumidori Kaiten Sushi Shibuya is a sushi restaurant in Shibuya, Tokyo, serving tuna and eel. Orders are placed on a tablet, and the sushi arrives at the seat on a train. Diners take a numbered ticket or register for the line by QR code, then browse nearby shops and bookstores while waiting. Ordered sushi comes out late, which breaks up the flow of the meal.
