McDonald's Guui Station is a small branch at Exit 4 of Guui Station in Gwangjin-gu, Seoul, selling hamburgers and McMorning items. Chicken Cheese McMuffin sets and Shanghai Burgers are listed as its representative menu items. It operates 24 hours, food comes out quickly for takeout, and staff take orders directly rather than self-order kiosks. The interior retains its 1990s to early 2000s decor and looks worn.
