Barclay Prime in Philadelphia is offering up the most expensive Philly cheesesteak you'll ever see. As you can imagine, it's no ordinary cheesesteak. Kobe beef, Taleggio cheese, heirloom tomatoes, and instead of mushrooms and peppers, truffles and foie gras. It comes on a fresh brioche roll, dressed with truffle butter and mustard made by the restaurant. It's certainly not your classic four-buck model from one of the joints down the street.
Naturally, it's a publicity stunt.
To me, the ingredient list looks like something that an American cuisine Iron Chef would have come up with when the secret ingredient is thin-sliced Kobe beef and he's a dish short of goal with three minutes left. I think it certainly sounds delicious... but then, truffles and foie gras are frequently used as very expensive cousins of garlic butter... you can put them on ANYTHING and people will be all over it.
