With the plethora of sushi restaurants opening in the area, Shuhei's dominance has diminished greatly. I used to lunch here quite often and would always leave with a fishy taste in my mouth after eating the sushi. Additionally, it is an older restaurant and the age shows when you go there. The furniture and walls definitely have battle scars and just seem a little dated.
I would check out Wasabi or Pacific East before stopping in a Shuhei. They are all in the same neighborhood, so why not?
