Housed in the 1895 building behind the Opera House, Operakallaren contains four restaurants, a cocktail bar, and event rooms. The main dining room reflects the history of the building in the carved oak paneling, ornate chandeliers, paintings by Oscar Bjorck, and large arched windows. Chef Stefano Catenacci serves French cuisine, such as mushroom and black truffle risotto with olive emulsion, scallops with sorrel sauce, and lamb sweetbreads with greens. The well-respected Nobis wine cellar contains 30,000 bottles, including house brand champagne and whisky. Done in dark blues and grays, the bar overlooks the waterfront and the Royal Castle.
