Looks like a lot of my fellow reviewers will disagree but I found Roka Akor to be all style no substance. Don't get me wrong the food was good, but I've definitely had better sushi at places that are much less expensive. Making cool designs on my plate with the sauce does not make it worth the extra money. I went because I had a Groupon. I would never go there at full price. Sitting at the bar and being able to watch the cooks was nice. They have an open kitchen right there in the dining room. And the cocktails we ordered were very good (and pretty strong!).
I wouldn't necessarily discourage anyone from going to Roka Akor, but I personally think it's too pretentious and you could definitely find better sushi place in the Scottsdale area.
