Choi Naengmyeon Main Branch in Gangdong-gu serves san ojingeo mulhoe naengmyeon, a cold noodle dish built on raw squid. Shredded squid, cabbage and other vegetables sit in a sweet-and-sour red broth, and the Hamhung-style starch noodles, pulled in house, arrive in a separate bowl. When you order, the broth and chilled side dishes come out first and the noodles follow shortly after. The restaurant has a long history, and the portions of squid and vegetables are on the small side.
