Task: Question Answering
Input (English): passage: A drinking establishment is a business whose primary function is the serving of alcoholic beverages for consumption on the premises. Some establishments may also serve food, or have entertainment, but their main purpose is to serve alcoholic beverages. There are different types of drinking establishment ranging from seedy bars or nightclubs, sometimes termed ``dive bars'', to 5,000 seat beer halls and elegant places of entertainment for the elite. A public house, informally known as a ``pub'', is an establishment licensed to serve alcoholic drinks for consumption on the premises in countries and regions of British influence. Although the terms are increasingly used to refer to the same thing, there is a difference between pubs, bars, inns, taverns and lounges where alcohol is served commercially. A tavern or pot-house is, loosely, a place of business where people gather to drink alcoholic beverages and, more than likely, also be served food, though not licensed to put up guests. The word derives from the Latin taberna and the Greek ταβέρνα/taverna.
