The Dominion Theatre is a large West End house near Tottenham Court Road, best known for mainstream musical productions and big touring shows. It is not London's most intimate theatre, but it handles spectacle well and is easy to combine with Soho, Bloomsbury, or the British Museum.
Check what is playing before building an evening around it. When the right production is in residence, the Dominion is a straightforward, central choice for a polished West End night out.
