This trip, Guy Fieri's going from coast to coast and to the Great Lakes to dig up some dynamite dishes. In Los Angeles, a Mexican joint in Grand Central Market servin' outrageous octopus tostadas and their lights-out spin on a burger. Then, in Norfolk, Va., a bistro turning out grown-up, gourmet grilled cheese. Plus, a righteous stop in Lansing, Mich. doin' it up right.
