Part 3. Exercise
The atmosphere and ambiance was really great, as was the service. The sushi on the other hand was awful, the Cali roll was so salty I didn't even want to finish it. We got three other rolls, the Chandler, the Tiger and Da Bomb, and they were all sub-par rice, falling apart, and so crazily chewy that it felt like I was trying to eat someone else's tongue. I hope that visual helps.

I drove pretty far because the reviews were raving about this place, and Groupon or no, it was a huge waste of my time and money. It was so expensive and so not worth it. Just save your money and buy Wal Mart sushi, it's probably better than this.
Answer:
NEGATIVE
