Senne is a large cafe in the cafe alley of Seongsu, Seoul, selling coffee, baked goods, and desserts. Customers choose from four kinds of beans and can also order drip coffee. The cafe occupies the first and second floors of a building with full-length glass windows, with a select shop on the second floor and outdoor tables in the front yard on the first floor. Because the space is large, seats remain available even when Seongsu is crowded.
