In summer months, Buckingham Palace is open for tours. While I heard there were long lines to get in, I must of gotten there at the right time and walked right in. The first part of the tour is through public rooms in the palace, including seeing the banquet room set to perfection. Then, it was on to the gardens in the back — and an outdoor cafe for tea and sweets.
As a kid this is the place I would love to play, finding lovely places to hide. It made me feel like a child.
