Cheongdo Son Kalguksu is a noodle shop inside Bongdeok Market in Nam-gu, Daegu. It serves kalguksu, kaljebi, and eotang guksu made from aged dough rolled out with a hongdukkae. A line forms from around noon, and diners can take as much spicy gochu as they want. The parking lot and the shop are small, and the shop is hard to find inside the market.
