Restaurants fall into several industry classification based upon menu style, preparation methods and pricing. Additionally, how the food is served to the customer helps to determine the classification. Historically, restaurant referred only to places that provided tables where one sat down to eat the meal, typically served by a waiter. Following the rise of fast food and take-out restaurants, a retronym for the older "standard" restaurant was created, sit-down restaurant. Most commonly, "sit-down restaurant" refers to a casual dining restaurant with table service rather than a fast-food restaurant where one orders food at a counter. Sit-down restaurants are often further categorized as "family-style" or "formal".
