Fast food restaurants may be commonly referred to as quick service restaurants, burger joints, drive-thrus, diners, or grab-and-go eateries. "Fast casual" is another term used to describe restaurants that serve food quickly but with slightly higher quality ingredients and higher price points than traditional fast food chains. Some may use the term "junk food" or "convenience food" to describe fast food. Other slang terms for fast food restaurants include "greasy spoons," "roach coaches," and "belly bombers." Regardless of the name, fast food restaurants continue to be a popular choice for people on-the-go who want a quick and convenient meal.
