Iunsunai Guksu is a noodle shop in Nohyeong-dong, Jeju, serving ganjang bibim-guksu, red gogi-guksu, and anchovy gogi-guksu. The signature ganjang bibim-guksu mixes minced meat and chewy noodles the way jajangmyeon is mixed, and rice is then mixed into the remaining sauce. The red gogi-guksu has a spicy broth slightly hotter than Shin Ramyun with pork hock-style meat, and the shop has single-person tables. Kong-guksu is made from domestic soybeans ground to order and uses chewy medium-thick noodles.
