Arizona Smashburger is quite possibly the best burger I've ever had (including the ones I make at home). Smashfries are hit and miss (sometimes not that hot, sometimes too oily, sometimes over/under seasoned, rarely perfect...but when they are, oh MAN)...same thing with the haystack onions. But even when this location has a line out the door I find the service to be good and wait times minimal.
I should note that this fine establishment proudly serves Cherry Coke.
