A pub is in several countries a drinking establishment licensed to serve alcoholic drinks for consumption on the premises. The term first appeared in England in the late 17th century, to differentiate private houses from those open to the public as alehouses, taverns and inns. Today, there is no strict definition, but the Campaign for Real Ale (CAMRA) states a pub has four characteristics:

1. is open to the public without membership or residency
2. serves draught beer or cider without requiring food be consumed
3. has at least one indoor area not laid out for meals
4. allows drinks to be bought at a bar
