The establishment is flawless. The staff is some of the nicest ever, and is the perfect cherry on top to the best food in Arizona. I have no shame in saying Shake Shack has the best cheeseburger in town. There is not a single thing I would change about their cheeseburgers. That's not even the only thing, don't even get me started on their shakes and concretes. Their shakes and concretes alone are enough to make every other ice cream place around go out of business. All in all, Shake Shack truly does offer the 3 best things any restaurant can have --friendly and perfect staff, the best shakes and concretes, and most importantly the best cheeseburgers in the state.
