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.
An unassuming glass door on an otherwise plain facade hides a cavernous space, with high ceilings and huge sliding partitioned walls producing excellent exhibitions in a space you'll want to go back to.
The Barbican has so much to offer! From beautiful architecture, to a conservatory, amazing art, films, music and performances. It is such an exciting and relaxing place to hang out. Even if you don't have a purpose for visiting the Barbican, it's good for just having a tea with a friend.
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.
