This two-floor flagship shop takes inspiration from Diagon Alley. Inside are a Ukrainian Ironbelly dragon, a full-sized Knight Bus, a Leaky Cauldron-themed food-and-drink area and Oxford Street exclusives; Butterbeer is also available.
The official pages do not state whether general entry requires a ticket or what it costs. The separate Hogwarts Bear Ceremony requires a booked timeslot; booking is free, and the bear experience costs £75.
The shop is worth visiting in its own right for its themed interiors and striking Harry Potter details, even if you are not looking for a particular souvenir.
