01 / ABOUT THE PLACE

About this place

At lunchtime, Ryosui offers fish dishes including salt-grilled mackerel, simmered yellowtail and sashimi. One diner who ordered the mackerel set meal on a weekday noted that it came with several small sides. It makes for a lunch where grilled fish is the centrepiece, with a little of each accompaniment to enjoy alongside it.

A diner who chose the simmered fish at lunch remarked that care had gone into the side dishes as well as the main. For a change from grilled fish, options include simmered yellowtail, yellowtail grilled with Saikyo miso, and half a dried-at-night tilefish.

A visit report from 2025/6 describes a seafood rice bowl served with savoury steamed egg custard for 1,350 yen. It featured white fish, including sea bream, with a little sea urchin and salmon roe. The same diner noted that the number of lunch servings seemed limited, so an earlier arrival may be worth considering if the seafood bowl is what you have in mind.
