Rungki is a Taiwanese restaurant in Seoul that serves beef noodles and lu rou fan. It sits on the second floor of an alley in the Euljiro traditional market, offering a rich beef noodle broth and lu rou fan close to the local style, with cilantro served on the side. The two-level space has red interiors and 1990s Hong Kong film music. There are not many tables, so a wait can form.
