Dinner until 10 PM
One thing the staff noticed about the Christmas dinner is that the royal family doesn’t eat very much. Even though they’re behind closed doors, they still have to exhibit behavior befitting of a member of the royal family. This means not overloading their gullets with meat, carbs, and desserts. They’ll finish their dish and never ask for seconds.
Dinner usually lasts until 10 PM. However, they’ve finished eating long before then. After dinner, they go back to their favorite pastime, which is drinking. They’ll drink (lightly, of course) until around 10 PM when the queen calls it a night.
