Heaven in the heart of ugly Vauxhall. This peaceful and enchanting spot used to be squatted and has a very bohemian feel to it. Don't miss the secret garden with mosaics made of cups and plates. The food in the Italian deli is delish, a guy called Richard cooks it.
This is one of the only buildings in London that can lift depression. Each concrete block in the building is hand cast and hand hammered. Certainly the best bannisters in town.
Tate Modern can always be relied on for offering up interesting, challenging exhibits, housed in great architecture and with one of Londons best cultural bookstores. An ever reliable weekend hangout.
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...
