i've never had one but this thread makes it sound like i'm missing something big.
Equivalent musically to never having heard or played Chopin!
OK, that's a bit of hyperbole, but if you ever get to the East Coast, preferably Philly or New York you owe it to yourself to order one from the masters in any Little Italy neighberhood.
If you are anywhere near a Penn Station franchise store, they make pretty good ones also.
You can make excellent ones yourself (see above) but you need THIN meat and good rolls, not those heavy dense clunker things.
Goodbye, I'm salivating again.
