Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it's packed then The Red Lion is just up the road.
This may not be much of a secret but deserves a mention. I find it hard to go anywhere near this place without having to go there. Freshly baked Beigels hot salt beef and it never closes, 24 hours a day 7 days a week.
This is pretty much my favourite park in London, especially in summer. I can’t even count the amount of times I have done shoots there and it still continues to inspire me. I also recently discovered the pergola in Hampstead Heath and the only way I can describe the place is like a beautiful secret garden and you have to take a look at this place if you’re in the area.
