Demmers Teehaus is an Austrian tea shop in Roppongi, a four-minute walk from Roppongi Station and near the National Art Center. It carries a range of black teas and serves Sachertorte alongside a Sacher blend. Tea arrives in a pot and pours about four to five cups, and the first-floor seating holds around ten people. Seating is limited, so a full room means waiting.
