What they call a rib sandwich is just an order of ribs and two pieces of white bread. Not pulled pork, but ribs. Bones and all. The bread comes on the side so you would have to make the sandwich yourself. Maybe they're trying to cache in on the McRib popularity which is stupid.
This was really dissapointing, since Kenny's Smoke House used to be a great place. Or maybe that was just when it was Hogs on the Hill.
