Overall, service is terrible and food is average quality. We ordered several entrees and they messed up my order twice. I ordered the Kahuna Cheeseburger with the meat well done. The order came out and I asked for Ketchup. The waitress never came back with the ketchup. When I cut my burger in half, it was medium rare. The chef fixed it and brought it back 20 mins later. When I bite into it, it was so bitter bc apparently the chef burnt the pattie but felt the customer will not taste the ashy burnt pattie? If I could, I would have made the chef eat it and see how he like it. It took them almost 30 mins to remake the order again. By then, I have totally lost my appetite from waiting almost an hr for my entree and requested for my food To-Go. Towards the end, the Manager did come to our table to apologize. He gave us a coupon for 2 free appetizers for the next visit which we gave to our neighbor. May be our neighbor will have a better experience than we did. But we would not return to the Kona Grill in Scottsdale Quarter due to poor service (0.5 star)and the food quality did not wow us (2 stars) and since the Manager acknowledge the situation and try to make it better, we gave another 0.5 star so total, they get 3 stars from us.
