Michelle Obama and her daughters continued the Grand Tour on Monday with a surprise trip to London, where they visited Big Ben and the Tower of London and made a stop at 10 Downing Street with Sarah Brown, wife of the prime minister. The VIP tourists delighted British fans with a stop at the Audley, a pub in the exclusive Mayfair district. The family spent more than two hours at the pub; the first lady had sirloin steak, Malia and Sasha traditional fish and chips. The White House is keeping mum on the trip itinerary -- no word on how they'll celebrate Sasha's 8th birthday today.
