I lived in Philadelphia for 6 months and got addicted to cheesesteaks (Geno's, Pat's, Chink's, Jim's, and even Genuardi's Deli!). Since moving to Florida, the only good Cheesesteak places I found were Big Al's and Zio's (both in Delray Beach). They both have great steaks, but I prefer Zio's only because the parking is easy, you can eat inside wth air conditioning (it gets hot in Florida during the summer!), and the bathrooms are cleaner and easy to access. But if you want to grab a great authentic Philly cheesesteak, Big Al's (or Zio's) is the place!
Pros: The Cheesesteaks!
Cons: Bathroom is hard to access. Outdoor seating only.
