Casey Webb's tasty travels bring him to Manchester, New Hampshire, for an epic portion of barbecue that's served on a shovel at KC's Rib Shack. At local favorite Mr. Mac's Mac and Cheese, he only has eyes for their magnum opus, the Deluxe Cheeseburger Mac. Finally, Casey heads just outside of Manchester to Smoke Shack Southern Barbecue, where he bellies up to the ghost pepper-infused Inferno Burger Challenge.
