Typically, star ratings appear in guidebooks and newspaper restaurant reviews. The Mobil and American Automobile Association's system uses five stars, while the Michelin system uses three. The five star systems cover a wide range of restaurant styles and price ranges; whereas the Michelin system focuses on restaurants in the upper price bracket that excel at offering a fine dining experience.
Both Michelin and Mobil star ratings are based on rigorous restaurant checks by trained inspectors. These are conducted anonymously to prevent restaurants putting on a good performance solely for the inspectors. The objective assessment of food quality, service, presentation and atmosphere aims to produce reliable ratings that the consumer can trust.
A Mobil five star restaurant excels in every respect, from the décor to the food. Famous chefs usually run these restaurants. The four star restaurants also promise excellent food and service and are often found in good hotels. Three stars denote a competent, affordable place with a good atmosphere. Two stars are associated with quality, family-oriented restaurants, often with a theme or focus on ethnic cuisine, while one star is awarded to restaurants focusing on offering value for money. Pizza places and self-service restaurants fall into this category.
