Pirultz Coffeehouse (Yong-san) is a retro kissaten-style cafe in Yongsan-gu, Seoul, near Yongsan Station, selling coffee and desserts. Its signature is Vienna coffee, and pudding is listed as a representative dessert. The indoor seating is not large, so a wait forms on weekend afternoons. When there is a wait, customers are asked to leave after an hour and a half.
