I worked at the Barbican for several years and during that time became very fond of its architecture. One of my favourite spaces within the centre is the conservatory, a giant tropical garden in the middle of a concrete city.
Rotorino is a lovely little Italian, intimate but casual spot in East London. The food is great and when the weather is good - having your wine and pasta outside is nice.
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.
I grew up in the countryside, and if you're ever in need some instant escape from the city, this place is like a time warp. It's a huge space full of over grown mausoleums and graves, feels like a movie set. They also do tours.
