This is my favourite place to have a morning coffee in London. Its real chilled and the music is always perfectly set to welcome the day in, its usually something I have never heard before too. The coffee is good and the tip jar they have is the best tip jar in the world so make sure you bring a bag of pennies. Sit with your sketch book and have a lil think.
It's a members-only library but you might be granted access with a research request. The writer's room is great but there's a few special, hidden corners among the bookshelves to tuck yourself away in.
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.
