This is a small, wonderful, Mom & Pop restaurant. When I say that, I mean it. A Japanese couple runs it. Nobody else. You will not find 47 different kind of "rolls", you will not find cream cheese and avocado, you will not find weird experimental food. What you will find is amazing sushi. The menu is only two pages long, but it is all fantastic. (The rolls they do have are the right size, not the giant ones most places sell).
Oh, and don't plan on a quick dinner. But, do plan on an amazing one.
