Restaurant guides review restaurants, often ranking them or providing information for consumer decisions (type of food, handicap accessibility, facilities, etc). In 12th century Hanzhou (mentioned above as the location of the first restaurant,) signs could often be found posted in the city square listing the restaurants in the area and local customer's opinions of the quality of their food. This was an occasion for bribery and even violence. Today, restaurant review is carried out in a more civilized manner. One of the most famous contemporary guides, in Western Europe, is the Michelin series of guides which accord from 1 to 3 stars to restaurants they perceive to be of high culinary merit. Restaurants with stars in the Michelin guide are formal, expensive establishments; in general the more stars awarded, the higher the prices. The main competitor to the Michelin guide in Europe is the guidebook series published by Gault Millau. Unlike the Michelin guide which takes the restaurant décor and service into consideration with its rating, Gault Millau only judges the quality of the food. Its ratings are on a scale of 1 to 20, with 20 being the highest.
In the United States, the Mobil Travel Guides and the AAA rate restaurants on a similar 1 to 5 star (Mobil) or diamond (AAA) scale. Three, four, and five star/diamond ratings are roughly equivalent to the Michelin one, two, and three star ratings while one and two star ratings typically indicate more casual places to eat. In 2005, Michelin released a New York City guide, its first for the United States. The popular Zagat Survey compiles individuals' comments about restaurants but does not pass an "official" critical assessment. In the United States Gault Millau is published as the Gayot guide, after founder Andre Gayot. Its restaurant ratings use the same 20 point system, and are all published online.
The Good Food Guide, published by the Fairfax Newspaper Group in Australia, is the Australian guide listing the best places to eat. Chefs Hats are awarded for outstanding restaurants and range from one hat through three hats. The Good Food Guide also incorporates guides to bars, cafes and providers. The Good Restaurant Guide is another Australian restaurant guide that has reviews on the restaurants as experienced by the public and provides information on locations and contact details. Any member of the public can submit a review.
Nearly all major American newspapers employ food critics and publish online dining guides for the cities they serve. A few papers maintain a reputation for thorough and thoughtful review of restaurants to the standard of the good published guides, but others provide more of a listings service.
