good food. consistently slow and lousy service. I had forgotten that it was nearly exactly a year since I'd been here, and had the exact same experience (and my companions remembered too). Very attentive manager, but indifferent servers ... unbelievably slow. It took an hour and a half since we arrived to go from order to meal. Twice I had to get up and ask the manager about the status (oh and we ordered sushi, which doesn't need to be cooked!).
Food was very good though. So if you want great food without caring about the wait, or attitude of the staff then Kona Grill is the place for you!
