A piano bar (also known as a piano lounge) consists of a piano or electronic keyboard played by a professional musician as a central part of an establishment that also serves alcoholic drinks. Piano bars can be located in a cocktail lounge, bar, hotel lobby, office building lobby, restaurant, or on a cruise ship. Usually the pianist receives a small salary plus tips in a jar or basket on or near the piano, especially from patrons requesting a song. Such requests are traditionally written on a beverage napkin.[1] Some piano bars feature a baby grand or grand piano surrounded by stools for patrons (or, an upright piano or digital piano encased by a cabinet resembling a grand piano). Others have a bar surrounding the piano or keyboard.
