An establishment that serves alcoholic drinks — beer, wine, liquor, and cocktails — for consumption on the premises. Bars provide stools or chairs that are placed at tables or counters for their patrons. Some bars have entertainment on a stage, such as a live band, comedians, go-go dancers, or strippers. Types of bars range from dive bars to elegant places of entertainment for the elite. Many bars have a happy hour to encourage off-peak patronage. Bars that fill to capacity sometimes implement a cover charge during their peak hours. Such bars often feature entertainment, which may be a live band or a popular disk jockey.
