Restaurant guides review restaurants, often ranking them or providing information to guide consumers (type of food, handicap accessibility, facilities, etc.). One of the most famous contemporary guides 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, very expensive establishments.
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.
