The film studios that brought the magical world of Harry Potter to the big screen are available for Christmas parties. This year’s allotted dates for exclusive events have all gone, but the team’s taking enquiries for 2019. There are also tables of 10 or 12 available at a shared night on Wednesday 5 December. Bedecked as ever with real props and costumes from the films, Hogwarts Great Hall will host a suitably grand dinner. Dresscode is ‘Yule Ball’.
