RE: Roadfood Songs
It's not famous, but the Castle of the Jaguar really exists (so I'm told), and it plays a prominent role in the Tom Russell song, "Cuban Sandwich," which includes this wonderful chorus:
It's got two kinds of pig, ham and roast pork,
A slice of white cheese as long as your fork.
Put in a pickle, and if you're ever in New York,
Say "El Cubano" -- that's a Cuban sandwich.
