My sister and I always take my mum to London a couple of times a year. In a couple of weeks we are going again and have matinee tickets to see Beautiful. Originally the plan was to go to the Sky Gardens first and have a quick lunch. Unfortunately, when I tried to book there were no tickets left and the Bistro there has a special function on so can't book that either. Does anyone have any suggestions of where we could take my mum to kill a few hours before the show?
