If you're looking for "the best Arizona burrito in Phoenix"...this is the place to go. This is the best Mexican drive-thru driving. Very close drive from the Sheraton, the University of Arizona downtown campus, and close to Chase Field to get yourself a quality Arizona burrito before the game.
I also had the Mar y Tierra quesadilla, it wasn't my cup of tea. So if you want to get something else, this isn't the review you should read...but if you're indecisive, order yourself an Arizona Burrito.
