The beautiful weather (well, apart from the odd bit of torrential rain) makes this summer the perfect summer for picnics. Of course, making your own picnic treats and packing them up in a pretty basket is a lot of fun, but if you want a lovely picnic at minimum effort, then Fortnum and Mason’s hamperlings at the Serpentine Pavilion sound divine. A picnic afternoon tea for 2 is £25, which seems quite a bargain. – Miranda
