On this trip, it's Flavortown at its freshest. In Maui, Hawaii, Guy Fieri stops by a food truck for hamachi straight from the sea, served up on chilled soba noodles. Then, an empanada empire in Houston, Texas, is dishin' out churrasco and chimichurri, and a Chicago hot spot known for their homemade chorizo is crankin' out three different concepts from one kitchen.
