A disused car park in the backstreets of Hackney Wick isn’t an obvious place to escape the stress of London, but turn down an alley (stay with us here) and you’ll reach Grow, a little haven along the River Lea. Everything is apparently locally grown and fairtrade, but the main headline is that there’s an excellent riverside setup that’s hard to beat, and on a sunny afternoon it’s full of locals watching kayakers and paddleboarders coast along the water while sipping cold drinks and eating halloumi and pulled pork buns. There are usually DJs and live bands at the weekends as well, so it’s also easy to make a night of it with a few mates.
