Seongsu café quiet after 3pm, wide tables and window seats: T Coffee
T Coffee is a large café on Achasan-ro near Seongsu Station in Seongdong-gu, Seoul, set one floor below ground with floor-to-ceiling windows and wide spacing between tables, which makes it easy to settle in with a laptop or a book. The cheese cake (7,500 won), closer to a cheese tart in shape, was the standout, alongside a vanilla cold brew latte (7,000 won). T Coffee can fill up before 3pm, so arriving later gives you the calmest seats in the room.
