In the old royal garden, if you come to the UK to see the changing ceremony of Buckingham Palace, you may encounter this park. The park is not big, mainly green space, a small lake. The lounge chairs on the green space are charged, £1.8 an hour, and the price is favorable for a long time. The biggest problem with the park is that there is a toilet finally, and there is a charge, 20p, many Chinese people wait in line to go to the toilet. The toilet is not clean, but if you have waited for a long time at Buckingham Palace, if you need it, just it!
