This is definitely a unique experience to try at least once with someone you can talk to and cooperate with!
If you are wondering how dark it is, you can't see your glass when it is at your mouth.
The wait staff get you to hold their shoulder as they lead you to your table. Your food will be passed to you at shoulder height so you can put it down in front of you. I recommend putting your drinks to one side of the table so you know where it is and have less chances of dropping it.
I had the grilled octopus appetizer and it was really good! I was worried after ordering the filet mignon but luckily it was already cut into bite size pieces.
Note, make sure your hands are clean. Touching your food and plate may be necessary to find your food and see if you are done.
