Service: pretty good. Young kids working, so it's the service you'd expect at a fast food place.
Cleanliness: all the tables were biased when we came in. Restaurant has a modern vibe to it. Very crisp and clean. We sat outside to eat. They have metal tables, probably not the best decision in Arizona.
Food. It's okay. It was bad. It was "omg good" it was simply, okay. No better way to put it. Probably not good enough to return, but not bad enough that I wouldn't recommend to someone. Burgers were greasy (as you'd expect) and fresh and hot when we got them. Fries were excellent. The sauce bar is a nice touch. Another Yelp review mentioned sweet potatoes and the toasted marshmallow sauce - excellent.
