Diners, Drive-ins and Dives 18x4

This trip, Guy's rollin' out for a festival of flavors. In Portland, Ore., the Guamanian food truck serving up righteous shrimp fritters and a unique spin on chicken salad. In Wheat Ridge, Colo., the family-run comfort food joint crankin' out killer cannoli and kraut burgers. And in San Francisco, the fusion food truck combining Filipino and Latin traditions in adobo buffalo wings and grandpa's recipe for pork tacos.
