Dark
Via Eric and Christina: the latest branch of a unique restaurant opens in Beijing, China. These so-called dark restaurants put a twist on the dining experience: you eat in complete darkness, guided to your seat and through the meal by visually-impaired waitstaff wearing night-vision goggles.
The goal is two-fold. One is to increase employment opportunities for the visually-impaired and raise awareness of the challenges they have to overcome. A second is to enhance your appreciation of the taste of the food by shutting down one of your other primary senses.
Add that to the list of novelty dining experiences, like Ninja Restaurant. There are Dans Le Noir restaurants in several major cities around the world.
The bathrooms, wisely, are brightly lit. There are some affairs one should conduct without the help of a spotter, for the benefit of both parties.
