Boundary is the kind of establishment cool enough to take your mates, but respectable enough to take your parents.
The venue has recently added a steel, timber and glass pergola - which full covers the dining area so that they are open every day and all year round - whatever the weather.
The wild herb theme, together with a canopy of grape producing vines makes for a treehouse feel. Very cool.

Queen Of Hoxton
Outdoor cinema, rooftop yoga, all-day BBQs and a series of craft events throughout summer - Queen of Hoxton has got it all.
With vibrant ice-cream colours, shady umbrellas, picnic benches and sun lotion dispensers, it is fully equipped for long hot summer days. As night falls continue to enjoy the outdoors, or head downstairs for a party in the ground floor bar.
Frank's is like discovering some magical waterfall after having to trek through miles of prickly jungle. Arduous, but worth it, and instead of jungle you have the grotty streets of Peckham and the piss-smeared floor of a multi-storey car park.
A long bar serving yum, reasonably-priced cocktails and cold beers, with a view that overlooks London. The staff are fun, the crowd is cool but not intimidating and you never stop feeling like you've stumbled on a genuine London secret.
This rooftop bar has an unbelievable view of St Paul's, great sofas and an upscale (but relaxed) atmosphere.
Just avoid it on Tuesdays through Fridays, when it's full of bankers guffawing into their two-third-pints of Heineken. Lovely on Sunday afternoons.

Dalston Roof Park is perched on top of a tower block in the darkest heart of east London, entered through an art gallery and seemingly endless flights of graffitied stairs. Boy is it worth it.
The city of London sparkles in front of you, there's artificial grass and sweet-smelling flower pots, candy-striped deck chairs and cushions to lounge on with a fruit cider, and the cheeriest bar staff in town. The regular outdoor cinema is held in the middle of the gorgeous rooftop allotment, and there's rotating pop-up food stalls.
Walking into Kensington Roof Gardens, you feel like you're in some kind of luxurious Spanish haçienda. The gardens are beautiful, there are (real) flamingos strutting about and the only piece on London skyline you can see is a gothic church.
Sure spirits are pricey, but the wine is reasonable. And it's much cheaper than jetting off to Spain.

The Roof Garden Bar, on the South Bank
Head up the winding yellow stairs above the Queen Elizabeth Hall and you'll find this great - and slightly hidden - summery spot, where they serve Greenwich Mean Time beers, Pimms and more.
Of course, the RFH terrace cafe below is nice, too - but you'll have better view over the Thames (and more of a chance of getting a seat) up here.
This is one of the best rooftop bars in London – just don’t go on a weekday! On a Saturday or Sunday however it’s one of the most peaceful locations you’ll find in this city.
Yes, drinks are fairly pricey (freshly squeezed orange juice will set you back more than some beers) – but the roof garden, relaxed décor and an amazing view of the City of London are definitely worth it.
