A restaurant that receives a 'B' or 'C' on its second inspection can opt to post a 'Grade Pending' card in the window while it waits for a hearing before an Administrative Tribunal at the Health Department.

Once the Tribunal rules on the inspection, the final score is recalculated and the restaurant must post the grade it receives.
 
In other words, if a restaurant has a 'Grade Pending' sign, it had enough violations to earn a 'B' or a 'C' and it is contesting the low grade.
