This sandwich:
is the nadir or acme of the Pittsburgh palate, it would seem. It's your choice of meat, cheese, cole slaw and french fries between two slabs of Italian bread. I'm not into them, but most people love them.
I vastly prefer the other Pittsburgh discovery, the Turkey Devonshire: an open faced turkey sandwich with a delicate cheese sauce, thinly sliced tomato, and bacon on top. It's much like the Louisville Hot Brown.
