This trip, Guy's hittin' up world flavors tucked away in the USA. In Los Angeles, the Korean-Mexican mashup serving up short rib tacos and spicy pork chimichangas. Nearby in L.A.'s Chinatown, the New Orleans-inspired joint cooking up Big Easy po' boys and legit crawfish mac and cheese. And in Charlotte, N.C., the Serbian pizza place dishing out European-style calzones and a stuffed cabbage specialty.
