Gentlemen's club

Reform Club, a prominent club in London since the early 19th century

A gentlemen's club is a private social club of a type originally set up by men from Britain's upper classes in the 18th and succeeding centuries.

Many countries outside Britain have prominent gentlemen's clubs, mostly those associated with the British Empire: in particular, India, Pakistan, and Bangladesh. There are also many clubs in major American cities, especially the older ones. A gentleman's club typically contains a formal dining room, a bar, a library, a billiard room, and one or more parlours for reading, gaming, or socializing. Many clubs also contain guest rooms and fitness amenities. Some are associated mainly with sports, and some regularly hold other events such as formal dinners.
