A tiny, grubby pub on Charing Cross Road in London, invisible to Muggles, serving as the gateway between the Muggle world and Diagon Alley through a brick archway in its back courtyard.
The Leaky Cauldron is the seam between worlds. On one side, Muggle London with its traffic and office workers. On the other, the hidden heart of wizarding Britain. Tom the barman, bald and toothless, knows everyone. When Hagrid brought Harry through, every witch and wizard in the pub wanted to shake Harry's hand — the Boy Who Lived, standing right there in the Leaky Cauldron, and he had no idea why they were crying. Professor Quirrell was there that day, stuttering his greetings. Harry shook his hand. Neither of them knew yet what that meeting would mean.
A small, dark pub squeezed between a bookshop and a record store on Charing Cross Road. Muggles' eyes slide right past it without noticing. Inside: dark wood, a long bar, a few tables, a crackling fire. The clientele is a mix of witches and wizards in robes and pointed hats. The back courtyard contains a brick wall — tap the right brick three times with a wand and it rearranges itself into an archway opening onto Diagon Alley.
