It’s inspired by none other than Doctor Who’s TARDIS. When the door is shut, it looks like a typucal replica of the Doctor’s time machine. But the door opens to reveal a Victorian-style bathroom, complete with checkered floor, a toilet, a sink, and a hand dryer.
The bathroom, aka Doctor Loo, is outfitted with motion detection sensors which turn the lights on or off as patrons enter and exit. The Loo’s creator and restaurant owner Justin Hoggars has also installed a doorbell of sorts that emits the TARDIS’s familiar wheezing sound.
