I went to Sushi J two weeks ago with my wife and a couple of friends. The entire meal was awesome. I only had sushi and sashimi, so I can't talk to the other items on the menu. However, everything I ate was very fresh and tasted fantastic.
The only things I would change: Colder beer and warmer room temperature. The beer was cool, but I like my beer very cold. The restaurant air temp was a little cold for me, but I think it was because it was chilly outside. That is all I would change.
I would highly recommend to anyone who is looking for great sushi and at a good price.
