For all those perverts out there - you'd think that the place is made for petty frolicking but there is a green light camera monitoring the place and making comments to waiters who all wear black clothes and a headphone.
It is really interesting to guess which food you're eating and to try and use knife and fork in pitch black. I'd managed to distinguish tuna from chicken but not lentils from rice. And bread became a very handy tool for delivering the food off my plate into my mouth. I wouldn't go twice but as an experience it was definitely worth it.
