I'm a fan of sushi buffets, but normally stick to the same two places. I decided to try Nagoya with some of my friends and I would say it was a good experience.
To me there a few things that are important at a sushi buffet, the variety of food, quality of taste & dessert!! Now this location didn't have that great of a variety of food, a lot of good sushi but not much else.. the food however was delicious, I enjoyed all of the sushi we ate! As for the dessert, there was basically nothing but ice cream and to me that is a disappointment!
The service was good, however, we were the only ones there. But overall, you could tell they cared and wanted to make sure you enjoyed the food. While everything overall wasn't bad, for lunch I remember paying up to $30 on a weekend to my knowledge. I believe they add service charge automatically.
