This one of those two places in one. Half of the store is a Carvel Ice Cream which I've never seen anyone use. It might be more popular during the summer. You will find a separate Yelp listing for this.
The other half is a Schlotzsky's sandwich store. I've loved Schlotzsky's since the one over by ASU existed . After classes I used to go there frequently. The Schlotzsky's original sandwich is so tasty. I wish this Schlotzsky's was closer to my part of Mesa, but its worth the drive.
