すし屋の根がみ (Sushiya no Negami)

Sushiya no Negami is a sushi restaurant in Sapporo run by a husband and wife, serving Hokkaido seafood sushi. The omakase course uses shari made with the Hokkaido rice Yumepirika, and includes ikura gunkan and sashimi. Ingredients are explained in Korean, and visits are arranged through a reservation site, with the owner couple handling guests directly. There is no sign outside the building and the entrance is down a basement staircase, making it hard to find.
