I Byeongtae Hamheung Naengmyeon in Yeokchon-dong is a naengmyeon restaurant serving mul naengmyeon, bibim naengmyeon, and hoe naengmyeon. It was opened by Lee Byeongtae, who worked as a head chef at Ojangdong Hamheung Naengmyeon for 50 years, and the hoe naengmyeon comes with a spicy and tangy sauce topped with hoe. Warm onyuksu is served before the meal, and the hoe naengmyeon is generously topped with hoe. The sauce on the hoe naengmyeon is on the spicy side, so it can be overwhelming for those who cannot eat spicy food.
