I've eaten in here a few times now and I have to say I am quickly becoming a regular. The lunch specials are crazy affordable and delicious.
There is usually a hibachi lunch special for $5.95 which includes a cup of soup, salad, chicken or steak hibachi, and two big scoops of rice. It's quite a bit of food and it's all really good.
They also have sushi specials for lunch. The last special I got consisted of three rolls (cucumber, california, and tuna), a cup of soup and a salad for $8.45. Everything was very fresh and tasty.
The staff is very friendly, almost too friendly at times :).
If you are in the Ballantyne area at lunch I suggest you give them a try!
