Noa's Roasting Lotte Department Store Gwangbok Branch is a coffee shop on the rooftop terrace on the 13th floor of Lotte Department Store Gwangbok in Busan. It sells Americano, iced flat white, bread, and desserts, and staff describe each coffee. From the observation deck outside the store, you can look out over Busan and take photos. At midday and on weekends it is crowded, so drinking coffee quietly is difficult.
