A bar is a long raised narrow table or bench designed for dispensing beer or other alcoholic drinks. They were originally chest high, and a bar, often brass, ran the length of the table, just above floor height, for customers to rest a foot on, which gave the table its name. Over many years, heights of bars were lowered, and high stools added, and the brass bar remains today. The name bar became identified with the business, (also known as a saloon or a tavern or sometimes as a pub or club, referring to the actual establishment, as in pub bar or club bar etc.) is a retail business establishment that serves alcoholic beverages, such as beer, wine, liquor, cocktails, and other beverages such as mineral water and soft drinks. Bars often also sell snack foods such as crisps (also referred to as potato chips) or peanuts, for consumption on their premises. Some types of bars, such as pubs, may also serve food from a restaurant menu. The term "bar" also refers to the countertop and area where drinks are served. The term "bar" derives from the metal or wooden bar (barrier) that is often located along the length of the "bar".
