Cult bar Sedmica does little to advertise its presence on the street. The clue is a small sign above a residential doorway. It’s the meeting place of people from the creative arts, an obvious rendezvous spot before a private view at a trendy gallery or for an impromptu cast party. You enter through a corridor lined with concert and exhibition posters. Inside, a small room contains a crowded bar counter upon which stand taps of Fischer’s and Erdinger. Long, thin marble tables provide a place to prop, otherwise you can join the boho crew on the wrought-iron mezzanine behind.
