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...

Lovely space in Southbank. Interesting events and exhibitions. I really like the surroundings as well, especially during sunny days. Walk around and then have a rest drinking facing the river.

Since The Columbo Group took over The Jazz Cafe, it's become the best programmed venue in the city, focusing on jazz, soul, funk, disco and afrobeat.

Open until late night.  Make sure to sit down for the best hand pulled noodles

This is a great, free and lesser known spot in London. A glass lift takes you up the side of st.Paul's cathedral right out onto the roof terrace of this shopping centre. A great view over London.
