The Apollo Theatre will remain closed until at least the beginning of January following its ceiling collapse last week.
While an investigation into the collapse is underway and a major clear-up operation is in place, performances of The Curious Incident of the Dog in the Night Time up to and including January 4 2014 have been cancelled.
The Apollo’s website described the collapse as "unforeseen circumstances" and advised people who had already booked tickets to contact the vendor for details of how to exchange or claim a refund.
Mayor Boris Johnson said, however, the rest of London’s theatre land remained "open for business".
He said: "London’s world renowned theatre land is open for business and thousands of theatre goers will rightly be out and about tonight and over the weekend.
"Westminster City Council and the Society of London Theatre have assured me that all safety checks for the West End’s historic theatres are up to date, but, as a precaution, further checks have already started and will continue throughout the day."
Andrew Cooke, chief operating officer at London & Partners, said: "We would like to reassure visitors that incidents like this are extremely rare.
"We welcome the fact that London theatres have said they will cooperate with authorities to reassure the public that venues are safe."
