[custom_adv] A coffeehouse, coffee shop, or café is an establishment that primarily serves coffee, related coffee drinks (latte, cappuccino, espresso), and – depending on country – other drinks including alcoholic. [custom_adv] Some coffeehouses may serve cold drinks such as iced coffee and iced tea; in continental Europe, cafés serve alcoholic drinks. [custom_adv] A coffeehouse may also serve some type of food, such as light snacks, sandwiches, muffins or other pastries. Coffeehouses range from owner-operated small businesses to large multinational corporations. [custom_adv] While café may refer to a coffeehouse, the term "cafe" generally refers to a diner, British cafe (colloquially called a "caff"), "greasy spoon" (a small and inexpensive restaurant), transport cafe, teahouse or tea room, or other casual eating and drinking place.

As early as the 1950s Beatnik era and the 1960s folk music scene, coffeehouses have hosted singer-songwriter performances, typically in the evening.
