Groupon deal for the day: NYC's Le Caire Lounge

A good hookah lounge is like a good science experiment-full of flavorful smoke and best enjoyed with a hummus appetizer and the lab partner you have a crush on.

Today's Groupon treats the senses to a sensual sensory experience: for $15, you get $30 worth of fruitily smoldering hookahs, signature cocktails, and Mediterranean meals at Le Caire Lounge on East 3rd Street.

Dare I say, smoking?
