Conveyor Belt Sushi in Monmouth/Ocean County?
Wow! You bought up a memeory of a little tiny place in Waikiki, Hawaii when I read your post. The sushi was probably the best I have ever had. It was such a small, tiny little place, but packed with locals!
Sorry I can't help you with a place like this in this area, but if you find one..please post!! (Although I know the fish won't be as great as Oahu!)
Like bqut1, I don't know of any "conveyor belt" sushi places in NJ. I did see reference to a place in NYC but it was described as "disappointing" and overpriced.
I used to visit Japan a lot and I can tell you that we went to the conveyor belt places only if we needed to eat very quickly. Without exception, the sushi was average at best with very little variety. The ingredients were fresh but it was apparent that they were not of the highest quality and the sushi chefs were kind of second or third tier, i.e. they would never get a job in a really good sushi restaurant.
