Have you ever tried this Korea noodles ? (Kalguksu)

Kal-guksu (Korean: 칼국수; English: Noodle soup) is a Korean noodle dish consisting of handmade, knife-cut wheat flour noodles served in a large bowl with broth and other ingredients. It is traditionally considered a seasonal food, consumed most often in summer. Its name comes from the fact that the noodles are not extruded or spun, but cut.
