A pub is a bar or tavern that serves food and often acts as a community gathering place. People visit pubs to eat lunch, to drink beer, or to play darts with their friends.
Pub is a shortened form of public house that dates from 1859. In the sixteenth century, a public house was first "any building open to the public," and then "an inn that sells food and drink." Today, the word pub is more or less synonymous with tavern — both are primarily places to drink beer, wine, or spirits, though a pub (especially in Great Britain) is seen as vital to its neighborhood, a cozy place to gather.
