Sin Sin Won is a Chinese restaurant on the second floor of Cheonji Building in the Starbucks alley behind Gran Seoul in Cheongjin-dong, near Jonggak Station in Seoul. Its jjajangmyeon comes with a thick sauce, chewy noodles, and large chunks of potato, while its kkanpunggi is fried until soft and coated in a sweet-and-sour sauce. This long-standing Chinese restaurant's buchu ganjjajang is lightly seasoned and lets the ingredients' flavors come through. Its jjamppong has a clean-tasting broth, though the flavor falls short.
