According to AFP:
Britain’s Queen Elizabeth II arrived in Paris on Thursday for an increasingly rare overseas visit…at D-Day commemorations…
The special treatment included seeking the monarch’s preferences for Friday’s banquet menu. “Very classic French” was the request relayed back.
After her arrival, the queen laid a wreath at France’s national monument to its war dead, the Arc de Triomphe, and then met Hollande at the Elysee palace for tea.
She then went on to attend a garden party at which she was to bestow honours on several British and French nationals.
