ICA (Institute of Contemporary Arts)

With two galleries, two cinemas, a theatre, bookshop, bar and café—all with free admission—the Institute of Contemporary Arts is a one-stop showcase of the best new art from Britain and around the world. Covering visual arts, music, cinema, educational talks and events, it is the perfect forum for all sorts of creative industries. Located in central London on The Mall, the institute hums until late at night thanks to extended hours (til 9PM) every day but Monday, when it's closed.
