Go to Japan town north of down town (Jackson and 5th street). There are several (more than 5) Japanese restaurants within 2 or 3 block range. But My favorite sushi house, Sushi Masa, is located at a mall near the cross street of Camden and Kooser in Cambrian area. That restaurant looks like a traditional Japanese restaurant from the looks, layouts, and the people, but I know the owner is Korean, or Korean Japanese, or Korean-Japanese-American, or whatever. Anyway they are good.
