Jangsaeng Geongangwon is a cocktail bar in Nonhyeon with an exterior that resembles a deer antler juice shop. It serves cocktails made with herbal and Eastern spices and ingredients, and each drink comes with an explanation of its story. On a first visit, guests receive house-boiled Hovenia dulcis water as a welcome drink, and potato chips and purple sweet potato chips are provided as basic snacks with refills. Most of the seating is at the bar table, so conversation is difficult for larger groups.
