For a Jack in the Box, this place is dirty. Yes that is saying a lot. It seems to be a hang out for downtown Tempe's transient population but I guess they cannot kick out the paying customers.
The service seemed a little slower than most locations but that could have been the decorum in the building that made me feel that way. The food is standard Jack in the Box fare, so at least you know what you are getting into. I just wouldn't step into the bathroom there if I were you.
