The name stands for one of a kind and this nightclub certainly lives up to its name offering unannounced celebrity guests, impromptu performances by hot new artists and surprises that keep coming night after night. The nightclub is located inside Mirage Hotel and does a great job of bringing New York City to Vegas with its artwork and interior design. There are two separate rooms in the actual club, each with its own bar and DJ booth, but you will have to pay only once to get in, and then you are free to mingle from room to room. Guests here should expect to pay anywhere from $30 to $40 for admission, and drinks start at $15, making it a pricey night out if you like to drink a lot. Dress code is upscale casual, collared shirts, closed toed shoes, dresses and absolutely no shorts, sunglasses or baggy clothing. Open on Wednesdays, Fridays and Saturdays from 10:30 pm until 4 am. Expect to wait in a line before you get in. Also, expect lots of dancing here, beautiful chandeliers and dark lit rooms, dressed up celebrities and a heck of a lot of fun.
