A bar is a hospitality outlet that serves alcoholic drinks like beer, wine, liquor, and cocktails, for consumption on the premises. Some may be stand-alone outlets; while others may be attached to hotels.
Also, a bar may be a part of a home; usually in the living room or the guest entertaining areas, where the liquor is stocked.
Bars usually have counters, at a height higher than usual tables because of the frequent use of people in a standing position. Bar stools or chairs are placed around the counters.
Some bars (in business establishments) have entertainment on a stage, such as a live band, comedians, dancers, singers etc. Bars which offer entertainment or live music are often referred to as music bars or nightclubs.
The term ‘bar’ is derived from the specialized counter on which drinks are served. Patrons may sit or stand at the bar and be served by the bartender, or they may sit at tables and be served by cocktail servers. The ‘back bar’ is a set of shelves of glasses and bottles behind that counter. In some establishments, the back bar is elaborately decorated with woodwork, etched glass, mirrors, and lights.
