I am definitely not precious about the materials I use to make my work, but every so often I find myself in need of something more specialised. L.Cornelissen & Son is a beautiful and well stocked art supply shop with extremely knowledgable staff.
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.
The best place for a glass of wine*. It's the perfect balance – not too formal, not too informal either. Food is consistently good. Lamb's Conduit Street is a little oasis in the midst of Bloomsbury. (*slightly overpriced)
The St Bride Foundation is the home of the St Bride Library, an incredible resource of printing history, in the form of books, printed ephemera, and tools from the trade. It also hosts many fantastic talks each year – check their website for details.
