We tried out this recently-opened restaurant in the Del Mar Plaza this Sunday and thought it was really quite good. (It is in the same spot as the sushi restaurant used to be, but has been extensively remodelled). I am far from an expert on this type of Japanese food, but I thought it was really good. The menu was not as varied as Sakura and Okan, and was certainly much more pricey. Apparently all of the veggies are organic and come from Chino Farms and I believe they said the meat was "local" as well. We tried a sashimi salad (excellent), specialty sushi roll (very good), gyoza (best I've ever had), tempura (good, but not as good as Okan) and a few other dishes I can't remember. We at a lot, and it was close to $50/person.
All in all a welcome addition to the neighborhood, but because of the prices I cannot put it on my everyday rotation. I realize the rent can't be cheap there and they use high quality ingredients, but I will have to reserve the spot for special occasions. I am not sure if the Del Mar crowd will warm up to this type of restaurant, but I sure hope it works out.
