Time Out says
Get a festival top-up at an outdoor movie screening – all in a good cause
With its laidback and festival-y vibe, Nomad is one of our favourite outdoor cinemas, popping-up in all sorts of kooky London nooks and crannies. This year, Paddington Street Gardens hosts 'Four Weddings and a Funeral' and 'Some Like It Hot' screens in the Festival Gardens of St. Paul's Cathedral. Best of all? All profits go to the Sustainability Institute, so you'll actually be helping the planet just by being there.

The season runs from May to September. Tickets for popular screenings sell out fast, so book early.
Bring a picnic, or tuck into Provençal street food from Madame Gaultier or Cheeky Burger.
