Slightly biased as this is where I live, but Stoke Newington is great place to spend lazy saturday / sunday afternoons getting sloshed with friends. There are 10 + pubs within walking distance who all are great places for one reason or another. I'll pick out the White Hart for its huge beer garden...
Audiophile paradise. Boasting one of the coolest looking and beautifully crafted sound-systems I've ever seen. More listening bar than club, it has a low key vibe with a diverse roaster of talented DJ's spinning an eclectic mix of tunes and full albums.
Ever since discovering this area around 6 years ago I still find it a nice area to go for a walk. Beginning at Paddington Basin with a mix of modern architecture which is fantastic to wonder around. Following the canal you go past a few restaurants and underneath a section of the A40 Westway before arriving at Little Venice and beyond.
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.
