Gyotore

The name is the menu: gyō (gyoza) and re (lemon). The gyoza are Kochi street-stall style — thin-skinned, fried to a crackle, with minced lemon peel folded into the filling — seven for ¥430, three dipping sauces on the side. Wash them down with the grated-lemon sour, pulp and all, which is entirely correct.

It's a short counter and a small table, a TV in the corner, and an owner who also runs a roast-sweet-potato food truck. Finish with the vanilla sweet-potato ice cream; it's the owner's origin story in dessert form.

Shin-Nagata is a few stops from Sannomiya and drinks a decade cheaper. This is a good reason to make the hop. Cash only, closed Sun–Mon.
