When was the last time you heard someone excited about eating hospital food? Probably never, right? But oddly, that hasn't stopped people from opening and others from enjoying successful hospital-themed restaurants. In fact, there are such restaurants and bars in Singapore, Taipei, Japan (with a prison hospital-theme sure to give you twice the nightmares), and Latvia. As gross as they are, they would be pretty awesome for a creepy Halloween meal.
You can check out more images of Hospitalis, the one in Latvia, at the link, but be warned, though it may be a restaurant, it may just make you lose your appetite.
