Angel-in-us Jamsil Lotte World Mall B1 is a cafe on the basement level of Lotte World Mall in Jamsil, close to the subway and bus transfer center. It sells roastery coffee, fresh fruit juice, and Yun Chef Bakery's campagne and ciabatta. There are more tables inside than are visible from the outside, and the seating area is fairly large. The seats are narrow and low, which makes them uncomfortable for staying a long time to use a laptop.
