This trip, Guy's grabbing sandwiches all over the country. In Denver, an auto garage turned restaurant serving regional favorites from Southwestern Green Chiliburgers to Maine lobster rolls. In Slidell, La., a little joint under the water tower putting their spin on a classic southern Po' Boy with house smoked prime rib. And in Indianapolis, a cafe in an old Victorian where the house favorite is an original pork and kale sandwich called the D'Nai.
