@farmerman,
you can ask them to use provolone. everything you wrote about is available. try their own red sauce, its damned good, but softens the rolls too much for me. a del's cheesesteak was about all i ate at Textile for lunch and dinner.
they are the best cheesesteaks in town. between noon and two pm on the week days you'll see about four philly cop cars aligned in a "west-philly" park, viz., with two tires in the street and two on the curb sitting on the corner of henry and wendover waiting for their cheesesteaks
i went to Philly Textile, '72-'76 about two miles east of del's, lasalle was my number three choice after villanova.
the easiest way to get there from center city is to take east river drive (or kelly drive) up the schuylkill river, get on wissihickon/lincoln drive heading northeast or away from the bridge that takes you to city line ave., turn right at the old police station, on gypsy lane (its about 1/2mile to a mile) then go up the hill until you get to west schoolhouse lane and take a left turn. stay on it until you hit henry ave then take another left onto henry ave. stay on henry ave until you pass the golf course that ends at walnut lane (about 2 miles). dels is two-three short blocks past the golf course on the right hand side of henry ave, sitting on a corner.
enjoy
and their hoagies are very good too!
