Harmonie Club (click here for address and info)
Although it was founded in 1852, it's been in its present building at 4 E 60th St since 1905, where people with fancy jobs who've been sponsored, seconded, and admitted gather for talks about politics, finance, real estate, health, and whether or not their sweater looks better tied around their shoulders or their waist. Most of its 1,000 members are Jewish. If you make it in, you can score eats from the mahogany-paneled Grill Room (with leather-cushioned bar stools and over-sized chairs) or the main dining room with 20ft ceilings and English white oak paneling. There's a Sunday Brunch buffet, a fitness center, squash courts, and a pool, of course. And a half-sized basketball court with an adjustable height rim, so you can set it to 7ft and dunk on your fellow zillionaires.
