HHSS HOUSE is a cafe on the third floor near Mangwon Station in Seoul, serving drip coffee, iced tea, and pastries such as scones. It is known as a place to read or work quietly while looking out at street trees and dense foliage through full-length windows. Reaching it means turning onto a back street and going up to the third floor, and with no signage the location is hard to find. It is not suited to conversation.
