Sakanayano Daidokoro Nijō Shijō Honten is a seafood rice bowl shop in Sapporo's Nijō Shijō market. It serves kaisendon topped with uni and ikura, along with a chef's special bowl, and the rice is seasoned sweet to match the seafood. The shop opens at 7 a.m. and usually operates until 2 or 3 p.m., so an early visit is required. Prices are on the higher side.
