Membership dues are in the thousands of dollars, clubhouses are often unmarked, membership lists kept top secret. The New York Social Club is still going strong after 174 years, unhurt by recessions, depressions, and even (gasp) the admittance of women. Some of the clubs aren't so secret anymore (ahem, Soho House), but that doesn't make it any easier to obtain membership...-

Here's a look at New York City's most exclusive Social Clubs, in no particular order:, in
