Ryu Changhui Guksu Gangnam-gu Office Station Direct Branch is a noodle shop near Gangnam-gu Office Station in Gangnam, Seoul, serving noodles and sujebi (hand-torn dough soup) in an anchovy and dipori broth, along with bossam. It sells a sujebi bossam set, kongguksu, and mandu, and kimchi and white kimchi are taken from a self-service bar. The anchovy and dipori broth is clean rather than harsh, and the noodle strands do not soften easily until the end. The sujebi is made from thinly rolled dough, which is a disappointing choice for those who prefer a thick texture.
