Been there just twice, first time servie was good, second just about ignored.  Asked for water the first time and had to ask again without any apology for forgetting.  Guess you have to expect from a Korean own and run restaurant.  Not too many real Japanese operated restarant in the area so I always expect so-so service and food from a pretend real Japanese cuisine. Must be the Korean culture to act this way, they are there just to make money and nothing else. Will never step foot there again.
