Dongdong Teahouse is a small rooftop teahouse in an alley in Yeonnam, Seoul, serving matcha and other teas. Its menu includes okumidori latte, matcha pudding, matcha panna cotta, and hojicha latte, and the yakgwa with vanilla ice cream contains salt. Reaching it requires walking through winding alleys and climbing to the rooftop of a small building. Mornings are quiet with a view, so it works for going alone.
