It's a good deal for the price:
lunch - $6+
dinner - $7-13
And of course, for this price, you have to accept that it is not the most authentic Japanese food you will have.
However, service is good. They provide complimentary edamame appetizer for dinner orders, where as most places charge you for that.
Nice interior decor for a restaurant like this. I'd say it's a place for a quick bite or light dinner.
