Jersey Mike's makes a pretty decent sandwich. Fresh bread, more meat than that other chain where Jared eats, and a whole salad's worth of veges on top. Great flavor to everything. I like the number 13 Italian. Decent cheesesteaks too. However, the prices are a bit steep for a chain.
This location is clean; and it's generally staffed with friendly people. TVs in the corners if you're trying to watch a game while eating your sandwich...but with the hard seats and lack of beer, I don't really see the point.
Overall, this is a solid choice for a sandwich in Ahwatukee. I just happen to know some other very solid choices too, so it's not my usual spot.
