I live North of Baltimore. We were going to make cheesesteaks on a campout so I asked a buddy from PA where to get the buns. He led me to the Amoroso factory store. What a dump...with incredible rolls. It was worth the trip.
And no, the cheesesteaks I made weren’t even a close 50th to Geno’s.
I remember reading in the paper years ago that the meat for steak sandwiches is I think an eye roast, frozen, and thinly sliced while still partially frozen (in order to get it sliced thin enough). And a 12’ roll holds about 1/2 pound of meat.
They don’t call it Filth-adelphia for nothing.
