A bar is a business 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. Bars which offer entertainment or live music are often referred to as music bars or nightclubs. 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 or a minimum purchase requirement during their peak hours. Such bars often feature entertainment, which may be a live band or a disk jockey playing recorded music. The term "bar" is derived from the specialized counter on which drinks are served.
