An unique experience restaurant in Paris

Dans le noir? (In the Dark?) is a restaurant located in Paris. They have opened more restaurants in London and Moscow.

Everything is unusual in there but it is really worth going.
The concept is having diner or a drink in a complete darkness, not even a tiny spot of light to help you figuring where is your neighbour.
All the waiters and waitresses are blinded people. If you need to go to the bathroom or anything else, they will be the only ones to ask.
You can either order for a regular menu or you can let yourself go for the "Surprise Menu" which you won't know the composition except that there are a starter, main course and a dessert. You will be able to ask the staff for the elements of the diner/lunch, once you will be done.
In this completely dark room, all your senses will be in alert. You will need to speak loud because you don't know the distance to your next friend, the food will take a totally different taste since you can't see it, some stuff you don't like, will taste pretty good now that you can't see it.
The restaurant is fully-booked every evening, so don't forget to book before going there.
