Sandongseong Yetnal Suta Jjajang is a Chinese restaurant near the Seoul Seobu Police Station that serves old-style hand-pulled jjajang and hand-pulled jjamppong. The noodles are made by hand, and the jjajang is stir-fried with large-cut potato and onion, either sweet or not salty. A warm tea comes with each order, and the hand-pulling of noodles can be seen in the kitchen. There is no parking lot, so going by car is inconvenient.
