A novelty experience worth doing once and then perhaps again years later.
There is definitely something to be said for eating in total darkness. It is incredible how difficult it is and it makes you realize how reliant on sight you are for the most basic of tasks. I was pretty much useless with a fork let alone finding my wine.
Conversation is somehow more intense as you lose all visual cues. There is a collage of noise and, in the darkens, you really have to focus on who is speaking to follow the conversation. It makes for a very unique experience.
Unfortunately the food is mediocre at best and that is what downgrades this to a novelty. If more attention was spent on the menu, it could be much more and would be likely something I would do more often or recommend with greater gusto.
