Grew up in Phila and thought all cheesesteaks were good. Had favoirites and thought life was good. Then I found Mama's in 1980 and it all changed.
It is an awesume sandwich. Large (which is good), on a great crispy roll, with good meat. The Pizza Steak version is by far the best with lots of meat, cheese and sauce. A great meal unto itself.
I moved to Chicago almost 20 years ago and come back to Phila a lot. Mama's is always on my list of places to see even if it is an hour from my family's house.
Pros: Taste, Pizza Steak, Meat, cheese, roll
