A bar is an establishment where alcoholic beverages are sold to be drunk on premises. It can be either an independent business or a section of a restaurant or hotel.
Alternatively, "bar" can refer to the specialized counter on which the drinks are served, and it is from this term that the establishment itself as a whole gets its name. Frequently when food is served elsewhere in the establishment, it may also be ordered and consumed at the bar. In Las Vegas it is common for the bar to contain up to 15 slot machines.
The "back bar" is a (sometimes ornate) set of shelves of glasses and bottles behind that counter.
In some parts of the United States, the term "bar" suggests an emphasis on hard liquor. In some parts of the country, this is actually a legal distinction: in Washington and Oregon, a tavern is restricted to beer, wine, and hard cider, but a "bar" has a full liquor license.
In the UK 'bar' is usually short for 'Wine Bar' where as the name suggests mainly wine is sold and drunk.
In Australia, traditionally the 'public bar' (hence pub) was where men drank, while the 'lounge bar' was where women drank. This is rarely the case in the 21st century, with many 'lounge bars' being converted into gaming rooms for pokies.
Bars range from down-and-dirty "dives," little more than a dark room with a counter and some bottles of liquor, to places of entertainment and the elegant watering holes of the elite.
