The best of the two department stores in Copenhagen, Illum is a temple to Scandinavian interior design and cutting-edge fashion. The brand selection is young and hip - think Acne, Paul Smith, All Saints, and D-Squared - and the building itself is a glamorous architectural destination. A tremendous glass dome arches over the whole affair, and lends a light touch to the interior, while a restaurant on the fourth floor yields excellent views of the city.
