You just opened up a can of worms Tony. Like Pizza or anything of this kind, you will get varied answers and of course, it is particular with what you like. Depending on if you prefer your meat chopped or slabs of ribeye, you could get redirected to different venues. Here are some of my opinions
Dalessandros: Excellent. Meat is very finely chopped up. Seasoned well. (15 minutes off the beaten path) Tends to be longer lines than others
Joes Steak and Soda: Becoming one of my favorites
Steve's Prince of Steaks: Delicious. Cant go wrong. Slabs of ribeye
Jim's: Been hit and miss with me but has a huge fan base. Go to the original establishment if you have a choice on South St.. Chopped meat
Sonny's: Very good. Slabs
John's Roast Pork: One of my favorites. Really really good. Chopped
Campo's: Dont bother
Ishkabibbles: Only had it once..was horrible...but some people swear by it.
Tony Luke's: Weak..gone downhill
Chubby's: Little place right across the street from Dalessandro's if you want to try 2 different ones right next to each other. Decent Cheesesteak
