Party-central Cafe Opera is adding some much needed pizzazz to the Swedish nightlife scene. Occupying a glassed-in terrace designed by acclaimed architect Peter Celsing in the 1960s, the Brass Bar is the new HQ for socialites, night owls and big shots on the town. The oblong elevated bar, a pattern of backlit stone and shiny brass, is like an homage to the seductive decadence of the 1960s and 1970s, with striking mirror prisms suspended above it - a bespoke design by Herman Persson of Koncept Stockholm. The guest list is selective, so few get to experience the intimate blue and violet velvet cocoon. Scandinavian grandeur at its finest.
