We took ourselves off to the museum , delightfully cool in the aircon - it 's around 35 outside . I was inspired by the olympic swimming and rushed into the refreshing river , picking my way through broken glass . Dinner was going to be at a nice hotel as a special treat but low and behold , no food . They were cleaning .
