Hongdae Gyodong Jjamppong is a Chinese restaurant in Seoul that serves jjamppong, jjajang, and tangsuyuk. The jjamppong has a strong pepper aroma with a thick, rich broth, and the tangsuyuk uses thick cuts of meat with a pronounced meaty flavor. Ingredients are stir-fried to order over high heat for wok hei, and the noodles arrive chewy rather than soggy. The broth and the tangsuyuk sauce are lightly seasoned.
