With Waffle House I guess you have to set your expectations accurately. You know your food will arrive fast and it will be typical greasy spoon type fare.
This particular location is a bit hectic and possibly a bit off with respect to consistency of food and service.
I guess this may be good if you were hungover, drunk, or just broke and in need of some sustenance. Other than that I would save your three bucks and spend 5 over at The Cracker Barrel as the Waffle at this Phoenix location was more like a flat, soggy, burnt biscuit.
