First licensed for beer only in 1862 as the Duke of Cambridge and only selling beer in half pints for a long time, it changed names in 1962. This attractive one-room pub on the route between Buckingham Palace and Westminster Cathedral, adorned with flowers in summer, is a haven for tourists, office workers and local residents. The wood-panelled bar has pictures of local scenes and politicians. Look out for the bull's-eye windows and the two paintings of the pub on the way to the toilets. A cosy place for a pint after (or instead of) visiting the sights. Food is toasted sandwiches only! The venue has a claim to be the capital's smallest single pub.
