Sushimaru is a sushi restaurant on Haseulla-ro in Gyodong, Gangneung, serving conveyor-belt sushi on the first floor and Japanese dishes in second-floor rooms. The menu includes tuna belly sushi, rainbow roll, California roll, and udon, and you can ask for no wasabi on the sushi. Using a second-floor room requires a reservation in advance, and going early in the evening gives a wider selection of conveyor-belt sushi. The conveyor-belt sushi selection is on the small side.
