difference between and tavern and a bar
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.
Taverns were places of business, where people gathered to drink and eat. An Inn is a tavern which has a license to put up guests as lodgers. Inns were generally establishments or buildings where travelers could seek lodging and, usually (but not necessarily) food and drink. They were typically located in the country or along a highway; before motorized transportation they also provided stables.
