Lunch at JaBistro is something I would actively avoid. Prices are high, selection low, and food was mediocre. The best of the lot was their demi-katsu sandwich, the least of it was their signature roll. Lunch, I would give a 2-star rating.
Dinner was much, much, better. I had their omakase and I found that to be good value; it had decent fish, a good selection, and plentiful. Bonus points on good shari. I would give this a 3-star rating.
The room is nice with yellow wood and modern black accents. The lighting is subdued, but not overly dark. They did a good job with bringing that all together.
I don't regret going to dinner (let's not talk about lunch), but wouldn't return. Would consider returning if friends wanted to go though.
