Designed in 1899 by Charles McKim of McKim, Mead & White, the University Club has one of New York's most stunning private spaces: the club's vaulted, frescoed library. Overnight rooms are available to book, and of course there's always a chance you'll be invited to a wedding or other event there. Otherwise, it's time to ask around to see who you know that's a member to get yourself a private tour!
