Knotted Donut Jongno HiKR is a cafe on the fifth floor of the Korea Tourism Organization building on Cheonggyecheon-ro in Jung-gu, Seoul, selling donuts, cakes and coffee. Its signature items are the milk cream donut and the mugwort cream latte, which is sold only at this location. Around 11 a.m. the cafe is quiet, and the wait at lunchtime is shorter than at other branches. Visitors take an elevator to the fifth floor, and the tables and chairs are uncomfortable.
