"English gentlemen's clubs"

A gentlemen's club of the traditional English kind is a private member's club open to upper-class men.  It would usually provide common areas including a bar, library and dining room as well as bedrooms for overnight stays.  Gentlemen chose their club based on family tradition, or a common interest or background: for example, the school or university college they attended, the part of the country from which they came, a particular political leaning, past military service or a profession in the Church.
