What each star level means
One star marks a very good restaurant in its category. Two stars mean excellent cooking worth a detour. Three stars mean exceptional cuisine worth a special journey — the phrasing is about travel, which is a legacy of the guide's origins as a tyre company's road manual.
Crucially, stars are awarded for the food alone. Comfort, decor and service are recorded separately in the guide's other symbols, which is why a three-star restaurant can be austere and a plush dining room can hold none.
