Photo Gallery - Food Corn butter ramen and spicy miso ramen. You must try ramen in Hokkaido, but this shop gets a lower rating of 2 1/2 stars. We tried the sushi restaurant called Triton (トリトン) and loved it. Marutoma Shokudo has very delicious uni. Onigiri (rice ball) with salmon, just a snack at a rest stop. The flavor tastes just like the melon. Unagi is really popular and has gotten a lot more expensive in recent years.
