Yes. You really saw what you just thought you saw. It’s a Mexican fast food joint in Adelaide, Australia named Burp. Naming restaurants after bodily functions is generally a bad idea. Giving a restaurant a name that even remotely sounds like a bodily function is not wise, either (think Taco Ria or Pu Ping Palace).
I’ve never eaten at Burp. Morbid curiosity has almost gotten the better of me a couple of times, but I just can’t bring myself to do it. I’ll post more photos of oddly named restaurants from time to time, and I’d love to hear other examples of poorly chosen restaurant names from you.
