Zen is a Chinese restaurant on the third floor of the Kyunghyang Shinmun building on Jeongdong-gil, across from Kangbuk Samsung Hospital. It serves meal dishes such as bokkeum bap and jjamppong, and the food is plated neatly. The interior is spacious with three to four open-room seating areas, which suits quiet gatherings. It draws many customers, so waits at weekday lunch can run over 30 minutes.
