A Look Inside The World's Most Elite Members-Only Clubs

Founded in 1963 in London's elite Mayfair neighborhood, Annabel's provides the best in food, entertainment, and general atmosphere. Plus, the underground venue is one of the few posh clubs whose average membership age doesn't hover around 60. Take heed, though: this fact doesn't diminish Annabelle's selectivity in any way. Two references are required to even begin the membership application process, and a strict dress code is still enforced. As an insider friend told us, "If you so much as take your blazer off on the dance floor, you'll be kicked out." [Photo via @guada_itfashion]
