A coffeehouse is an establishment which primarily serves prepared coffee or other hot beverages. It shares some of the characteristics of a bar, and some of the characteristics of a restaurant, but it is different from a cafeteria. As the name suggests, coffeehouses focus on providing coffee as well as light snacks. This differs from a café, which is an informal restaurant, offering a range of hot meals, and possibly being licensed to serve alcohol.
From a cultural standpoint, coffeehouses largely serve as centres of social interaction: the coffeehouse provides social members with a place to congregate, talk, write, read, entertain one another, or pass the time, whether individually or in small groups of 2 or 3.
