Dining in a completely dark room, unaware what’s on your plate while sitting next to a complete stranger may not sound like an ideal restaurant experience but it’s certainly an intriguing way to spend a rainy night in London.

Dans le Noir, close to London’s financial district, is a restaurant full of blind waiters and waitresses who become your eyes around the restaurant, whose original Paris branch opened in 2004.

In the bar with the light, you choose whether you want the fish, meat or vegetable, but the dishes themselves remain a secret, as do the ingredients of the “surprise” cocktails. Bags, coats and devices(设备)that light up, including watches and mobile phones, are kept in the bar. Placing your hand on the shoulder of your guide, you are led to a table in a black dining room that sets up to 60 people. And it is dark.

The waiters tell you when the food is being placed down in front of you, then the fun begins, trying to get food into your mouth, then identifying just what it is that’s on your plate, and finally whether you have missed any of it.

It’s also a great chance to break social convention and eat using your fingers. Those same fingers are also the only way you can tell how much wine you’re pouring into your glass.

The happy atmosphere in the dining room also made the night memorable. You can’t really avoid talking to the person next to you at the long tables and guessing what the dishes are certainly provides adequate fuel for the conversations.

All will be revealed at the end of the meal when you are led back out into the lit bar. Not only do you finally get to see what you’ve just been eating but also who you’ ve been talking to for the last 90 minutes.
