We got a Groupon to this place and were disappointed. The rice in many rolls seemed stale/slightly chewy/old, and the portions were very small. The shrimp tempura did not have actual tempura batter, but standard American breading, and the dipping sauce had an unusual taste. Servers took a very long time to bring drinks, even though the restaurant was not crowded, and orders we placed from the menu took extremely long to arrive. The wait staff seemed inexperienced or desultory, and some of the rolls did not seem very expertly made. I've had better sushi elsewhere, and won't be back.
