Newroz Kurdish Restaurant on Copley Road was given the minimum score after assessment on January 17, the Food Standards Agency's website shows.
It means that of Doncaster's 505 restaurants, cafes and canteens with ratings, 364 (72 per cent) have ratings of five and just two have zero ratings.
The food hygiene rating reflects the standards of food hygiene found on the date of the inspection, it is not a guide to food quality.
