Piu is a cafe in a Seochon alley next to Gyeongbokgung, in front of Yi Sang's house. It serves yogurt desserts, slice cakes such as Basque cheesecake and carrot cake, and bottled imported wheat beer, wine, and highballs. The space is larger than nearby small cafes and has both tables and couch-style seating. The coffee is strong and good.
