How New York grades restaurants

New York City health inspectors score violations in points, and lower is better: 0–13 points earns an A, 14–27 a B, and 28 or more a C. Every restaurant is inspected at least once a year, and the letter has to be posted in the window. A restaurant that scores 14 or more on the first inspection of a cycle does not get a letter right away — it stays “Grade Pending” until a re-inspection settles it, which is why some spots here show an hourglass instead of a letter. Cooked only ever shows a letter the city actually posted; we never infer one from a score.
