Butter & Shelter Yeonnam is a cafe in Yeonnam-dong, Seoul, set in a converted house, selling coffee along with butter sandwiches, butter bars, and cookies. The butter sandwich, its signature dessert, is filled with house-made butter cream, and other options include creme brulee and Dubai sand. There are window seats along the full-length glass, outdoor tables, and seats toward the back of the store where leaves are visible. Matilda cake, glace scone, and pistachio-flavored dujjonku are also on the menu.
