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