Probably as close to authentic as you can get in Arizona. The cheesesteak "wiz wit" is close to what you might find in Philly, although not quite as tasty. Their chicken cheesesteak is pretty good as well. There are a variety of options to add to your sandwich, such as 3 different types of peppers and mushrooms. Beware, the cherry peppers are very spicy! The sandwiches themselves are fairly large and you can easily share a full order with sides. Since they are open 24 hours, it's definitely a good option for when you are craving food late at night.
