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...
These giant spectral cylinders are great at different times of the day but my favourite time is around dusk when the buildings in the city start to light up. The Gherkin and the new Shard building are framed in the lowest ring then the shifting colours of the sky are almost split in the following ellipses.
Morito is a few doors down from it's well know sister restaurant Moro. This not long open tapas restaurant feels like it could be in a little back street in Barcelona. The food is great, and it has a buzzy but relaxed atmosphere. You might need to wait a little while for the table, but I promise it's worth it.
