The sushi is simply outstanding!
Too bad the rest of the experience is not at the same level.
You typically have to edge past a crowd to get a number - and then wait for your turn (inside if you're lucky or outside on the sidewalk if you're not).
The service is friendly and efficient and the place is clean - but the atmosphere is pretty basic.
Go here if you're in the mood for great sushi and not too picky about the overall experience. If, on the other hand, you want a fine dining experience, you'll be better off at a place like Blowfish in San Jose.
