Some types of bars, such as pubs, may also serve food from a restaurant menu. The term "bar" refers to the countertop where drinks are prepared and served, and by extension to the overall premises.

There are many types of bars, including sports bars, cocktail bars, wine bars, beer bars/brewpubs, dive bars, speakeasy bars, piano bars, karaoke bars, rooftop bars, pubs, club bars/nightclubs, hotel bars, whiskey bars, and theme bars, each offering unique experiences.

Restaurants focus on food and then drink. Bars focus on drink first, food is only secondary. Some restaurants actually have a bar section (as well as a restaurant) with light fare (lots of appetizers) as well as a full dinner menu, and lots of drink.
