Following the success of the Savoy Theatre the hotel was built next door to satisfy the demand for accommodation from the members of the audience. The first London Hotel to have fully plumbed-in bathrooms (about 1 for every 3 bedrooms) electricity throughout and lifts.
We long to dine at the Savoy but only in a party with a total of 13 guests. Under these conditions the Savoy wheels out Kaspar, an art deco wooden cat from the 1920s, who is given the 14th place with cutlery and bowl of milk. This tradition originated at a 1898 dinner held by Woolf Joel - see there for the spooky story.
During the 1920s, while the BBC was based in nearby Savoy Hill they often used the Savoy Hotel for their dance music broadcasts.
