Gyedan Ramen Magok Branch is a Japanese ramen restaurant in the Magok and Balsan area of Seoul that serves tonkotsu ramen and gopchang-topped ramen. The basic tonkotsu ramen comes with a rich broth and chewy noodles. Diners can add spicy sauce to make the soup spicy. The noodles, broth, and chashu taste familiar, so the ramen is not particularly distinctive.
