O Hansu Uyuk Myeonga is a beef noodle and fried dumpling restaurant in Seoyeouido, Yeouido, Seoul. Its Hong Kong-style uyuk tangmyeon comes with noodles in a rich beef broth, topped with plenty of cilantro and scallions. At lunchtime it fills with office workers, but tables turn over quickly and food arrives fast. Broth, noodles, and rice are refilled for free, and fried dumplings can be ordered to match the number of people, though the portions are not large.
