Time Out says
An afternoon tea from Fortnum & Mason already ranks pretty high when it comes to searching out a great scone in London, but they're striving for new heights with this summer experience taking place at The Shard. 40 picnics will be available each day for guests to enjoy 800ft above the city on the 72nd level of the building which boasts an open-air deck. Feast on sandwiches, scones with strawberry jam and clotted cream, tea fancies and tea or coffee from a heavenly hamper. Make it an extra sweet escape by adding a bottle of Fortnum & Mason champagne to the mix (£135 for two people). Booking essential.
