I've told that the best sushi restaurant around Urawa is Takara-zushi located by Gyokuzo-in.
But the one I went last night was also fantastic.
This is Sushi Tsukato, which located near Riki.
Not to mention the wonderful taste of Uni (Sea urchin), I fell in love with its Engawa (= Fluke fin).

Anyway I also like the design of Unomi (= tea cup), a small child attaches like this.
