bar.

The term "bar" is derived from the specialized counter on which drinks are served and is a synecdoche applied to the whole of the drinking establishment. The "back bar" or "gantry" is a set of shelves of glasses and bottles behind that counter. In some bars, the gantry is elaborately decorated with woodwork, etched glass, mirrors, and lights. When food is served elsewhere in the establishment, it may also be ordered and eaten at the bar.
