I came across it by chance and went in for lunch one day. I had the Japanese curry with brown rice. I happened to be in the area again the next day, and because I liked it enough I went back for another lunch. This time I had some soup, a brown rice ball (triangle) with crushed sesame seeds on the side of it, and tea. They have several varieties of the brown rice triangles. I then also got two more brown rice triangles to go!
They do have an English menu, so if they don't offer it, ask for it. Items containing fish are marked accordingly.
From Honmachi Stn take Exit 12. Once at street level go right to the covered shopping arcade, and again right into the arcade. It's about a block or so down the arcade, on the right, at an intersection.
