Pat's is the Flagship of the Steak Sandwich. Located in the Italian Market and open 24 hours 365 days a year. Pat's does one thing,: Steak Sandwiches. Pat's is an outdoor dining experience. Even in the wee hours of the morning in the middle of winter, you can find yourself in a line waiting for a steak sandwich.

Learn the proper way to order:  Type of sandwish (steak, cheese steak, pepper steak), type of cheese (Provolone, Cheese Whiz, Cheddar), and with or without onions.  It's come out something like, "Pepper steak, Whiz, 'wit'").  And have your money ready; they don't take kindly to people who fumble for their money or have to borrow from friends while there are people waiting behing them.

Consider going across the street and getting in the line in front of Geno's.  Many Philadelphia natives will tell you that between these fierce competitors, Geno's is generally considered to be somewhat better.
