Cafe Jinjeongseong, which began as a small café in Gimpo’s Hangang New Town and later expanded to Incheon, Gwangju, and Jeju, opened its new location on top of Yanghwa Bridge in October 2024. True to its name, "Jinjeongseong" (meaning "sincerity"), the café uses organic ingredients and has gained popularity for its healthy beverages. Situated on the southern end of Yanghwa Bridge, the café is divided into two sections: the Tea House on the east side and the Coffee House on the west. The Tea House offers Korean traditional woojeon green tea and house-ground matcha, blended directly by the barista. The Coffee House serves signature drinks including milk tea and coffee.
