Bongsanok, located near the Seoul Arts Center, specializes in manduguk (mandu soup), known for its signature spicy twist with a generous sprinkling of chili pepper powder. The restaurant’s celebrated manduguk features Hwanghae-do-style mandu, stuffed with a savory blend of minced meat, kimchi cabbage, bean sprouts, and chives, all served in a rich beef brisket broth that has been meticulously boiled for twelve hours.
