Gansui is a Japanese restaurant in Okaido, Matsuyama, serving Uwajima-style tai meshi. The dish mixes sea bream hoe, raw egg, and soy sauce into rice, and diners choose between wild, farmed, or a half-and-half mix. Tables are guided so diners can learn how to eat it, and food comes out relatively quickly, so the line moves fast even when there is one. The amount of sea bream is on the small side.
