A veteran of conveyer belt sushi restaurants, I was excited one had opened up here in Phoenix. However, I have to agree with the comment that they are "as fine as McDonald's" because the sushi I had there wasn't very tasty.
However, their greatest faux pas is not mediocre sushi; it's location. If they were up by ASU, there's no question they would be busier. But they are way out in a strip mall in SW Tempe, and I was one of only two customers at the dinner hour. I hope they get more of a lunch crowd.
If I were them, I'd 1) change location. They're open til 11pm, so they should be around a college or more populated area. 2) put sensor strips on the bottom of the plates so they can tell how many times the sushi has gone around. The same plates kept going by the whole time I was there, and who knows how long they had been on the belt. 3) The unagi I had was pretty good, but the tamago was tasteless. Figure out which items are tasty and which could be improved. Then improve them.
