The Cheesesteak Philly Sub comes with shaved steak, melted Swiss cheese, and grilled onions on a toasted sub roll, while the new Chicken Philly Sub comes with chicken.
The price is about as low as it gets for a cheesesteak (or reasonable facsimile thereof) at $1.99 (although I'm guessing the sandwich is probably also on the small size but still, cheap is cheap).
The twin burger chains are also offering new, limited-time Garlic Parm Fries & Stix, a combination of seasoned fries and their signature Monsterella Stix (so-named for their "monster flavor" rather than because of any gigantism on their part) topped with a garlic parmesan butter sauce with grated parmesan cheese. Price is $2.99 for an order (may vary).
