Fluc (Praterstern 5, Vienna) – this is an indie rock club that has an indoor and outdoor section, which is popular during the Summer months. Both live events and DJ sessions are held here. Some would be surprised to hear that this was once an underground pedestrian passage that was converted into a nightclub. The club’s top floor (Fluc Café) showcases wacked-out live, experimental, electronic and indie acts. This place is open seven days a week.
