I've been a regular for more than 20 years. Sushi is excellent. I often take my sea-food monger friends to this restaurant.
I agree that parking is sometimes a problem, just as many other restaurants along the Montrose. I parked a few times across the street. Service sometimes gets very slow, when everyone apparently orders sushi same time :) from tables and from sushi bars. So this is not your pre-theater or pre-movie dinner restaurant. But, sushi is good.
