On the day that the next Harry Potter book is released, a retail strip in Chicago will transform itself into the shops of Diagon Alley, the High Street of Harry Potter’s world.
Starting about 9 p.m., the Magic Tree children’s bookstore will become Flourish & Blott’s bookstore, Cafe Winberie morphs into the Leaky Cauldron, and C. Foster Toys will take on the appearance of Quality Quidditch Supplies…
Even US Bank will become Gringott’s Wizarding Bank, with goblin-led tours to its basement vault.
