I came with a group of 12 friends for this experience. We went for their 4 course lunch menu. I picked savory.
They walk us in a group holding shoulder to shoulder to our table. Once you enter, you really are in pitch black nothingness. You're extremely vulnerable and need to rely on your server.
It is definitely an experience that I think everyone that's willing to try, should try.
I found myself using my hands to feel out my plate before using my fork. It was really difficult figuring out if we ate all our food or not or whether it was dropped in our lap. It was quite cold in the restaurant so maybe bring a light sweater if you get cold easily.
It's interesting trying to figure out your food relying merely on your taste, touch, and scent.
My favorite dish was my last course. Since this is supposed to be a mystery I won't ruin the guesses. Overall, it was a different experience and that's basically what you're paying for. The food was meh. But the service was good. I was pretty full at the end. I'm not sure if they've enhanced the menu to be more filling but my group was full.
Would I come back again? Probably not. The food wasn't screaming amazing but the experience was great!
