The Marines' Memorial Club

The Marines Memorial Club in San Francisco, California at 609 Sutter Street (at Mason), is a private social club for United States Marines and other veterans of the United States Armed Forces. The nonprofit Marines Memorial Association owns the large building in the Union Square neighborhood of San Francisco that houses a hotel, theater, restaurant/bar, sports club, special event facilities, library, museum, memorial, and a military history bookstore.

I am a member of this club. It's not so much a "private club" as much as a nice hotel in SF for former military... Nice location, first class accommodations at a fraction of the price of - for example - the Sir Francis Drake.
