Cardiff's New Theatre is a handsome Edwardian venue just off the civic centre, hosting drama, comedy, dance, pantomime, and touring musicals. It has the sort of traditional theatre atmosphere that feels different from the city's arenas and modern performance spaces.
It is an evening rather than daytime attraction, so check the programme before building plans around it. When the bill is good, it makes a natural cultural finish after the castle, arcades, and museums of central Cardiff.
