I was for few days at Scottsdale and accordingly to tripadvisor reviews I tried the bandera restaurant.
Great place, nice people, waiters looks nice and gentle.
I tried the Blackened Rib-Eye and waou, the best piece of meat I've ever eaten for a while.
With the cajun seasoned and a great french wine, just try it and enjoy ;-).
The only negative point would be the price 35$ for the meal and as well for the wine.
But try it at least once because it's Worth.
