Café Bohne is a quaint café at the Catholic University in Freiburg. From Monday – Friday it serves fair-trade-coffee, deserts and sandwiches throughout the day! The Milchkaffee (Large cappuccino) is the speciality with a thick layer of milk foam and chocolate powder to top. A student favourite! The foundation of the café has its roots in an initiative group from the Catholic University who were involved in the style of the café and placed importance on fairly handled products.
By the way: If you bring your own cup you will have to pay 10 ct less for all hot beverages.
