Our intrepid food explorer heads to the New England state of New Hampshire. In the state's largest city of Manchester there is an eclectic mix of cuisines from all over the United States. For a taste of barbecue Casey goes to KC's Rib Shack for their Feedbag Shovel. With a huge selection of comforting styles of mac and cheese, it's the Deluxe Cheeseburger he tries at Mr. Mac's. Casey battles the Inferno Burger Challenge at Smoke Shack Southern Barbeque. This is a one pound ghost pepper burger and two pounds of ghost pepper fire fries all consumed within 20 minutes.
