Definitely top five but I think there is better. Try Taylor Gourmet on H ST NE; easily the best Philadelphia style Italian in the city.
Also A. Litteri does an incredible chicken parm and can outclass the others if you mix and match it right. 9" hard roll rocks.
Not a huge fan of Taylor cold cut sanwdiches (or maybe their other stuff is just better), but their Pattison Ave (roasted or braised pork, sharp provolone, and broccoli rabe) has come pretty close to unseating Litteri's Classic Italian 9 inch with hot peppers as my number one. Taylor's chicken cutlet sandwiches are also really good. Get the 12 inch at Taylor and split it or save it for the next day, or else you get slightly ripped off
Toscana, near union station makes a killer chicken parm dinner for like 10 bucks for takeout. Hard to finish the whole thing (chicken plus pasta)
