A small, shabby-looking inn on Charing Cross Road, London, sandwiched between a big book shop and a record store. The Leaky Cauldron my not actually be in Diagon Alley itself, but it does serve as a "bridge" between the two worlds. The pub was built by Daisy Dodderidge around 1500 "to serve as a gateway between the non-wizarding world and Diagon Alley."
