The Queen has travelled the world during her 70-year reign, attending official royal engagements and meeting some of the most important and influential people in history.
And many of these grand occasions involve her sitting down to a very fancy dinner.
But the Monarch has never actually revealed her favourite food - and there is a very clever reason behind it.
Former royal chef Darren McGrady has previously revealed some of the foods she likes and dislikes, but not very many people know what her favourite food is.
A royal insider has explained that the Queen doesn't divulge the secret before travelling so that she isn't served the same thing everywhere she goes.

Former royal correspondent Gordon Rayner, who has covered more than 20 royal tours, discovered this fact from someone who worked with the royal family.
He explained to The Express : "As one of her staff told me, 'If she said she had a favourite meal she would never get served anything else.’"
Someone from the team will also go on a ‘reconnaissance’ mission before the Queen eats there to make sure it's up to standard, and if not, to make any necessary tweaks.
"The Master of the Household department will be in the reconnaissance party to tell foreign chefs not to cook anything with garlic or too much spice for fear of giving the Queen bad breath, and not to cook shellfish or anything that could cause food poisoning," he added.
Although she has never openly revealed what her favourite food is, we do know how much she loves a chocolate cake thanks to the former royal chef and author of Eating Royally Darren McGrady.
"The Chocolate Biscuit Cake is the only cake that goes back again and again and again every day until it's all gone," he told baking website RecipePlus.
"She'll take a small slice every day until eventually there is only one tiny piece, but you have to send that up, she wants to finish the whole of that cake."
