Sinjang Myeonok is a naengmyeon restaurant in Geumcheon-gu, Seoul, serving Hamhung-style hoe naengmyeon, mul naengmyeon, and dumplings. The hoe naengmyeon comes with spicy-sweet seasoning, chewy hoe, and springy noodles. Ordering naengmyeon brings onyuksu right away to drink while waiting. The basic mul naengmyeon and hoe naengmyeon have mild sweetness and sourness, so sugar and vinegar need to be added.
