A perfect place to have a nice cup of tea and sandwich. Or a scone and jam if you prefer. Tea and Tattle is one of my favourite "get away from the crowds" place. At street level you'll find a charming bookstore that specialises in books on art and culture. Pop downstairs to the delightful cafe.
Should I share with you where it is? Oh that is difficult I want to keep it my secret. Ok I'll whisper in your ear, but don't tell anyone. It is opposite the British Museum.
