I am Japanese-american and travel quite frequently to Japan and tried this place twice. Once was really a big disapppointment as I order the "Sashimi Dinner" Quality of the fish was average but what was really poor was the thickness of the slices. The thinnest sashimi that I ever had. I was invited for dinner there for someone birthday and again I notice the thinnest of the sushi over rice.
Although I only live 1/2 block from that place, I usually go to other Japanese restaurants near convoy.
