Here's some more history you may wish to add to your 'pitch':
"The Chicago Athletic Association was a private club whose plush chairs and well-dressed waiters recalled the days when it was an enclave for the city’s elite. But like other such clubs, it couldn’t survive changing times and the end of the three-martini lunch. It closed in 2007, but left behind a grand property on Michigan Avenue."
