Behind the scenes

 * The precedent article the is never capitalised in the book, making it possible to believe that it's not actually a part of the name. However, it is used every time the restaurant is named. Therefore it is practically a part of the name, in the same way that the precedes the Doctor, the Master and the Rani.
