Would you like a Star rating displayed outside Restaurants?

a local Authority to enforce a Star rating to be displayed on the windows of restaurants,this would give an insight to the cleanliness service and quality of the eatery.What i’m saying is a consumer(excuse the pun)has no idea what sort of place he/she is going into unless they are from the immediate area of the eatery.A star rating would make the owners of these places strive to offer the best that they can and also let the general public that they aint going to get a plate full of botulism.Thoughts please
