Bottom line this restaurant is not your typical Japanese restaurant. The interior is modern, and if it weren't for the sushi bar being visible you wouldn't know you were in a Japanese establishment.
The portions are small, for the price but the food tastes good The presentation of the food is also quite nice.
If you want more traditional Japanese food, in a more trad. setting then this place isn't for you.
Every table gets a three portioned sample dish with salted peanuts, nori (Seaweed), and kimchee.
Also every table get's a little skewer with frozen grapes with your bill, after you've finished dining.
To sum it all up, if you like Japanese food and you like bigger portions try one of the older Japanese restaurants in town.
Ginza in Willowpark would be the one I would suggest.
