Great food and atmosphere in Brixton. Try their Vegan Viking pizza: Cashew cheese, pistachio pesto, red chillies, rocket and mint or their Cauliflower cheese arancini. And who doesn't like a bottomless brunch in the weekends?
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.
They mainly sell art and cultural theory books but they also have a good selection of small press and self-published zines. It’s a great place to browse and get ideas.
Small restaurant on Highbury Corner that started off focusing on (basically) posh kebabs, but which is now producing some of London's most innovative dishes, focused around unconventional meats, cuts, and breads.
