Lotteria Lotte Baek Jamsil Gwangjang is a fast-food restaurant selling hamburgers and french fries, located in the underground plaza of Lotte Department Store Jamsil connected to Jamsil Station Exit 3. It offers shrimp burgers, bulgogi burgers, the Deri set, and the Deundeun Double X set, along with french fries. The store has three kiosks for ordering via touchscreen and opens early in the morning. Seating is closely spaced and insufficient, so it gets crowded enough that customers wait.
