Gogo Jeukseok Tteokbokki is a restaurant in Seoul that serves instant jeongol tteokbokki and sundae bokkeum. The tteokbokki arrives nearly cooked, with egg, ramyeon, jjolmyeon, and yaki mandu included as basic add-ins, and diners simmer it further to their taste. In the evening a wait forms, but tables turn over quickly and seats open up soon. The spice level is on the mild side.
