We go to New Concept frequently, both for lunch and dinner.
We have a mixture of vegetarians and omnivores in our family and we are alway happy when we leave.
The prices here are REALLY reasonable, usually our family of 4 walks out full at a tab of $40. I would get the bento box dinner, which has good tempura (they give you some shrimp), some sushi rolls, tasty miso soup, salad, rice and whatever selection of protein (I usually have the chicken). That is under $10 and it's a lot of food.
The only reason I don't give it 5 stars is the decor is SO boring. White walls and no art. If they bought a few cans of paint and did something on the walls it would be great.
I"m not calling this a high-end place. It is just basic japanese but good value for money.
