Felt Coffee Cheonggyecheon is a cafe facing Cheonggyecheon, selling coffee and dessert right in front of the Cheonggyecheon plaza. The coffee has a clear acidity, the decaf iced americano goes down cleanly, and decaf cold brew is also served. In good weather the full window wall opens and the space runs as an open layout with a bar in the middle. The wooden chairs and low tables are hard and uncomfortable.
