Cafe Sapun Sapun sits on the first floor of the KT&G building near Exit 5 of Gangnam Station in Seoul, and it is run by Jeonggwanjang. The cafe serves many drinks made with red ginseng extract, including a ginseng latte, and the red ginseng and ginseng menu items carry an actual red ginseng taste. Groups of six or more can reserve a meeting room, and the seats are spaced wide enough for reading or gatherings. A smoking room next door leaves a cigarette smell on the first floor, and some seats are hard chairs without backrests.
