Equivalent to 3 AA rosettes or 1 Michelin star

Imaginative, quality cooking of a very high standard, 
or authentic ethnic cooking with flair.
Equivalent to 2 AA rosettes or better

Highly Recommended 
Great cooking with fresh, local, ingredients, or a neighbourhood restaurant with consistent quality and reasonable prices.
Definitely worth a visit.
Equivalent to Michelin Bib Gourmand or 2 AA rosettes

Interesting, sometimes ambitious cooking that can produce some high quality dishes.  Equivalent to at least 1 AA rosette. 
May have aspirations to greater things, and may be improving, so should be tried.  Cafés with class

Not currently recommended for its cooking, 
but it may be improving and shouldn't be ruled out in the future.  
Or may be too limited in its menu for a higher grading. 

Very disappointing - think twice before visiting at the present time
