In continental Europe, a café is a traditional type of coffeehouse, but elsewhere the term "café" may also refer to a tea room, "greasy spoon" (a small and inexpensive restaurant, colloquially called a "caff"), transport café, or other casual eating and drinking place. A coffeehouse may share some of the same characteristics of a bar or restaurant, but it is different from a cafeteria. Many coffee houses in the Middle East and in West Asian immigrant districts in the Western world offer shisha (nargile in Greek and Turkish), flavored tobacco smoked through a hookah. Espresso bars are a type of coffeehouse that specializes in serving espresso and espresso-based drinks.
Several species of Coffea may be grown for the seeds. Coffea arabica accounts for 75-80 percent of the world's coffee production, while Coffea canephora accounts for about 20 percent.
The trees produce edible red or purple fruits called "cherries" that are described either as epigynous berries or as indehiscentdrupes. The cherries contain two seeds, the so-called "coffee beans", which—despite their name—are not true beans. In about 5-10% of any crop of coffee cherries, only a single bean, rather than the usual two, is found. This is called a peaberry, which is smaller and rounder than a normal coffee bean. It is often removed from the yield and either sold separately (as in New Guinea peaberry), or discarded.
The name "greasy spoon" is a reference to the typically high-fat, high-calorie menu items such as eggs and bacon. The term has been used to refer to a "small cheap restaurant" since at least the 1920s.
Since the 1970s, many Greek immigrants have entered the business. As a result, gyro and souvlaki meats are now a common part of the repertoire, often served as a side dish with breakfast and as a replacement for bacon or sausage.
