Chicago does not use letter grades. Every inspection ends in one of three official results: Pass, Pass with Conditions, or Fail. Pass with Conditions means violations were found but corrected on the spot or under a deadline β the restaurant is open, with homework. A Fail means serious violations went uncorrected, and it usually brings a re-inspection within days. Chicago also flags βpriorityβ violations, the ones most likely to actually make someone sick. Cooked reads Pass as clean, Pass with Conditions as mid, and Fail as cooked, and shows the itemized violations behind each result.
