Bongpyeong Naengmyeon is a neighborhood naengmyeon restaurant in Seoul that also serves hand-made mandu. The mul naengmyeon comes with a mild broth, while the bibim naengmyeon uses a spicy seasoning without capsaicin and a separate bibim sauce for adjusting the heat. An elderly couple runs the place, making the mandu daily and serving hot broth alongside. The mul naengmyeon and its broth are mild, so vinegar or mustard is needed.
