Michelin Guides (French: Guide Michelin (id mi.l)) are a series of guide books published by the French tyre company Michelin for more than a century. The term normally refers to the annually published Michelin Red Guide, the oldest European hotel and restaurant reference guide, which awards up to three Michelin stars for excellence to a select few establishments. The acquisition or loss of a star can have dramatic effects on the success of a restaurant. Michelin also publishes a series of general guides to cities, regions, and countries, the Green Guides.
