There are many quirky book stores in London, but I really love the selection that Daunt Books have, they often have bespoke editions which you won't find in other book stores. Also, the people that work there are so helpful and knowledgable. I can never stop myself from walking in!
Signature cocktails like "concrete", with actual chalk on it, food is good and the places has a small backyard garden. Recommend to try the food, as they are small tasty plates.
