University Blvd. and Euclid Ave., Tucson
Here you’ll find shopping for the college crowd and those who want to dress young. American Apparel, Urban Outfitters, and the like can be found here, as well as a few homegrown stores. Coffee houses and lunch spots make this a good place for shopping while eating.
Main Gate Square is right next to the University of Arizona  and so is frequented by students. There are 52 stores and restaurants on this block. Be careful about parking; instead of braving the back-in-only metered parking, go to the Main Gate Parking Garage (815 E. 2nd St.) and leave your car in shade and safety.
