A Quick Service Restaurant (QSR) is a type of eatery in the food service industry that focuses on providing fast and efficient service to customers. QSRs are characterized by their emphasis on speed of service, convenience, and a limited menu, often featuring standardized and pre-prepared items. Commonly known as fast-food restaurants, QSRs cater to customers looking for quick meals, often with the option of drive-thru services. Well-known examples of QSRs include popular fast-food chains that serve items like burgers, fries, sandwiches, and other easily prepared food items. The QSR model is designed for rapid turnover and high-volume sales, making it a prominent segment in the broader food and beverage industry.
