Taco Bell The Gangnam sits between Gangnam Station and Sinnonhyeon Station, serving tacos, burritos, and Crunchwraps. The Crispy Chicken Crunchwrap and the hazelnut chocolate sauce churros are listed as signature items. The shop also runs a cocktail bar, so highballs and slush cocktails can be ordered. The interior differs from that of other Taco Bell locations.
