The document provides definitions and classifications of different types of bars. It begins with a brief history, noting that the first bar appeared in Great Britain about 170 years ago and was invented by I.K. Brunel. It then defines key terms like "the bar", which refers to a specialized counter where drinks are served, and "bartender" or "barman", the person who serves drinks from behind the counter. Various types of bars are then classified and defined, such as wine bars, cocktail bars, beer bars, and mini bars, which provide snacks and drinks in hotel rooms.
