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.
A peaceful park in Kingston Upon Thames. You can see lovely houses and gardens across the river. It's a wonderful place where you can take a rest with your family or friends. I recommend you to take a walk after having lunch or dinner in riverside restaurants near to the park. It's not big, however, very enough to feel the beauty of nature. I've done some location drawings here which was quite exciting. Just seat on a bench and enjoy the comfortable atmosphere.
The Barbican is worth visiting for it's brutalist architecture alone. The concert programming is really diverse; it's home to the BBC Syphony Orchestra, but you'll also find bands like the Dirty Projectors and the National amongst the classical and contemporary composer line up. Plenty of art, dance and theatre too, however, the Conservatory is the real gem that's not to be missed.
