Northern Waters Smokehaus (Diluth, MN), Rainbow Drive-in (Honolulu, HI)This trip Guy's pulling up for a different kind of fast food. In Honolulu, Hawaii, a 48-year-old drive-in where burgers and dogs come with rice and macaroni salad. In Nashville, Tennessee, a Jamaican cafeteria at the farmer's market serving mango chutney chicken and curried goat. And in parking lots all over Los Angeles, California, a taco truck doing Chinese-Mexican fusion.
