Had the Classic Smash (a cheeseburger on a egg bun) for $5.39 with tax. Not quite as good as a $2.99 In N Out cheeseburger and way inferior to a Lobby's cheeseburger (my favorite). The egg bun gets soggy after a couple of bites, leaving you with a mushy mess. They seem to confuse the concept of a juicy burger with a greasy burger--this was just a greasy burger.
Pros: The store was clean and I was waited on promptly. The food arrived quickly and they have staff bus the tables rather than having customers dump the trays.
Cons: I arrived at 10:30am, the door was locked even though the sign said they open at 10am. When someone inside heard me pulling on the door they came to unlock the door. The real negative is that it is located at Tempe Marketplace, with its crazy parking lot and nasty hikes in the heat to the stores and restaurants. If I had not been here to see a movie, I would never have chosen this location.
