If you're looking for cheap, all-you-can-eat sushi you best look elsewhere.
Truly excellent sushi. The emphasis is on quality and craftsmanship. Don't let the shabby plaza belie the wonders within. This far East you can't beat it for authentic carefully prepared sushi.
Full Disclosure: I worked here over 10 years ago as a server and kitchen helper. I live over an hour away and I still stop in because the sushi really is that good.
