Starbucks Mangwon Hangang Park is a cafe inside Mangwon Hangang Park that sells coffee and drinks. Its large windows face the Han River and Seongsan Bridge, and drinking coffee while looking out at them is the way this location works. On Sunday mornings the window seats fill before 10 a.m., and by 11 a.m. all seats are taken. Because it sits on a floating structure, the building shakes when a large boat passes or the wind blows, which causes seasickness.
