I would definitely say I know what quality sushi is, and I've visited this restaurant several times before it went All You Can Eat, and it was a completely different experience then. The sushi was MUCH better and the restaurant had a better atmosphere. I've been to many All You Can Eat sushi places, and I understand that sometimes quality takes a hit when restaurants change to this type of dining experience, but it went down drastically. It is definitely overpriced, one AYCE after tax was $30. I've been to better places like Nagoya/Nagoya 2 and Sumo Sushi 2 that used to be a la carte and are now AYCE and their quality is still in tact at a lower price.
Overall, I'd say skip this place and find another AYCE joint. This place is minutes from my house, but I usually go to the other side of town for some good sushi.
