Tucked down an alleyway near Oxford Street is one of London's most exclusive and unique clubs, the Cirque le Soir. Translating in French to circus of the night, this dance club lives up to its name. Here, you can be anyone, and every night is a fancy dress party if you want it to be. My recommendation is to arrive before midnight, because after the clock strikes 12 the line starts getting pretty long.
Once you descend into the "underworld" there's an all night party waiting for you with circus performers, games, and vendors with popcorn and cotton candy. Make sure to explore the circus early because once 1 am hits the show starts: dancers, fire breathers, lasers, drag queens, living dolls; anything is possible. A night that I will never forget.
