Last year Frank Boxer, Paloma Gormley, Lettice Drake and Hannah Barry Gallery joined forces to create a pop-up art/food experience that was my favourite of the summer. They took over the roof top and top floor of the rather skanky Peckham multi-storey car park and created a sculpture exhibition and a restaurant on the roof.

It opens up again on the 2nd July and I'd really recommend checking it out. It's opposite Peckham Rye train station (12 mins from Victoria, London Bridge or Blackfriars) and open Thursday through Saturday until the end of the summer.
The menu is good though limited given the nature of the space. The atmosphere can be a bit too trendy for its own good at times but its a big enough space for it never to feel crowded and the views at sunset are just wonderful.
This is the official website with all the details.
