This trip, Guy's hittin' up world flavors tucked away in the USA. In L.A.'s Chinatown, a New Orleans-inspired joint cookin' up Big Easy po' boys and legit crawfish mac & cheese. In nearby East L.A., a Korean-Mexican mashup servin' short rib tacos and spicy pork chimichangas. And in Charlotte, a Serbian pizza place dishin' out Eastern European-style calzones and a stuffed cabbage delicacy.
