We have been huge fans of Ohya and eat at the Phoenix/Thunderbird location frequently. We were in Scottsdale at the movies and got excited to see they had a location where we were.
The restaurant itself is huge and the seats were super comfortable. The waitress was amazingly friendly and very helpful! The food is great- try the edamame appetizer, veggie tempura, spicy pork, Katsu, and chicken while you're there!
However, there were several differences between the Phoenix location and this one. The portion sizes were smaller and you need to sit at a grill top table if you want the BBQ items (at the Phoenix location, they will cook the BBQ in the kitchen and bring it to you regardless of what table you're sitting at). The Scottsdale location also didn't have the chicken wings appetizer (which are delish).
They lost some points from me for forgetting my dish altogether (we were a part of 4 and my dish was brought out when everyone else was almost done) and they didn't clear the dirty dishes away.
Overall, good food but my suggestion is to go to the location on Thunderbird for an overall good experience.
