If the wizarding world of Harry Potter (not to be confused with The Wizarding World of Harry Potter at Universal Studios, we’re talking about the one in the books) is anything like our world, there is a Starbucks on every corner. Like four in Diagon Alley. A full Starbucks café in the lobby of the Ministry of Magic. And at least one within walking distance of Hogwarts.
And they’re about to put that mom and pop shop Hogsmeade out of business: Because Sbux is now unofficially service butterbeer! We say unofficially because it’s part of their “secret menu” of unadvertised drinks.
