Gongju Kalguksu in the Daelim area of Seoul is a noodle shop that focuses on kalguksu. Its eolkeun kalguksu uses an anchovy broth with ssukgat added, in the style of jang kalguksu, and in summer a thick, nutty kongguksu is also served. In winter the shop serves kkomak bibimbap and kkomak bibim kalguksu, both with a generous amount of kkomak. The eolkeun kalguksu is only mildly spicy despite its name.
