This trip, Guy's pullin' in for a mishmash of comfort food. In Philadelphia, the low country joint dishing out unique North African chicken and sour cream pound cake. In Leucadia, Calif., the roadside taco truck going organic, stuffin' tacos with locally sourced meat, fish and vegetables. And in Phoenix, the boxing gym slash restaurant servin' up mac and cheese muffins and chicken pot pie in glass mugs.
