The Primanti Brothers Sandwich! I've actually been wanting to try one of these, but every time I'm in Pittsburgh I'm with some health nut types. Being born in England, the yearning for the "chip butty" is in my blood.
Do my eyes deceive me, or is that Primanti Bros. sandwich made with really nice bread?
What are the ingredients besides the fries, and are the fries made with some special seasoning?
My much older cousin used to tell of potato po boys in New Orleans, although I don't remember ever seeing them for sale anywhere. Here's one thing a little internet research uncovered: chezpim.typepad.com/blogs/2005/09/gourmet_survivo.html. (<-- fun blog, by the way) But can that be right? I'm positive the real potato po' boy is a glorious melding of fried (but not french fries) potatoes and roast beef gravy. *sigh* Guess I'll just have to experiment at home.
