Unlike restaurants where people go to see and be seen, diners go to Dans le Noir and other "dark" restaurants around the globe so they can't be seen. Dining in the dark means customers are deprived of sight, so their remaining senses become heightened. Smells become more pungent. The sense of taste becomes more acute.
Since opening in Paris in 2004, Dans le Noir (In the Dark) has served more than 100,000 customers in absolute darkness. Meals are prepared by sighted cooks in a separate lighted area. Drinks are concocted by a sighted bartender. But the entire wait staff is blind.
