Prohibited Sphere Megastore
From Tardis Wiki, the free Doctor Who reference
The Prohibited Sphere Megastore was a comic book store in London. Boneless had been pulling customers into the comic books in the store. The Twelfth Doctor and Clara Oswald visited the store to find the cause of mysterious energy fluctuations and disappearing people. Both Luke and a female clerk were working there, and explained what had happened. When the Boneless escaped the comic books, the store was partly destroyed. (COMIC: The Fourth Wall)
