Myeon 면 means Noodles in Korean and it includes all sorts of noodles - from cold noodle salads, hot noodle soups and more. BTW, Guksu 국수 also means noodles. Myeon is based in Chinese characters whereas Guksu is a pure Korean Hangeul.
Korean Knife Cut Noodle Soup (Kalguksu), Soba Noodle Salad, Makguksu and Jajangmyeon are some good noodle dishes that you have to try!
