The service is very good, and all the rolls (sushi, sashimi, etc.) are prepared fresh, not sitting on a serving plate (like you find in some Asian buffets). One of my favorites is the Mango Tango, in which each piece is covered with a slice of fresh mango. They also feature gyoza, yakitori, and other excellent menu items.
I would rate the prices as moderate, but when the food is good, that is not a huge problem. They used to have an "all you can eat" menu, but it has been discontinued.
The restaurant is ideally located in the "L Street Market", which is very close to the intersection of Interstates 80 and 680 (and is easily reached by most of the western/southwestern housing areas of Omaha).
Occasionally they have offers with Groupon/Living Social where you can pay $15 and receive a voucher worth $25 at the restaurant.
