Thank you everyone for recommendations. I ended up going to Jim's, Pat's and Geno's and having a cheese steak from each place with cheese wiz, green peppers and mushrooms ( I'm allergic to onions) and I would say Pat's was the best. I think Jim's had better mushrooms and Geno's had better green peppers. I didn't get to do anything else since the other person I was with wasn't finished until 5:30 and we had to travel about 30 minutes to get into Philly.
