The bar is used also as a staging point for mixing drinks, interacting with customers, and storing various equipment such as cups, garnishes, and so forth. When people do distinguish between a bar and a tavern, they usually think of a bar as an establishment where only alcohol is available, while a tavern offers food as well as alcohol.
Generally alcohol can only be served to the public on licensed premises, the pub (short for public house) being the most common place where to get a drink. In recent years more and more bars and clubs have sprung up, concentrating on a younger, more sophisticated and/or seriously affluent market segment.
