On rare occasions, I have found fresh banana leaves at Magruder's stores in VA, but I don't go to them very often, and I don't always find them when I do. I think it's pretty much of a fluke to find them fresh, but you can always find frozen ones at latin and asian markets.
I use them for tamales on occasion, and cochinita or pollo pibil, which it sounds like is what you are making--marinated with achiote, sour orange and onion and cooked in a banana leaf wrapper, the pre-industrial aluminum foil. I also use banana leaf wrapper for barbacoa de cabrito, which is goat shoulder marinated in a red chile adobo or mole rojo and steamed. For the goat dish I also use dried avocado leaves, which are harder to find than frozen banana leaves.
Just don't do what I did and decide you may as well use the whole package because what else are you going to do with the rest anyway? It was WAY too banana leaf flavor! Gag!
