Indeed, according to the fact sheet (http://www.nyc.gov/html/doh/downloads/pdf/rii/restaurant-gra...)

Initial Inspection. Every restaurant is scheduled for an unannounced inspection at least once a year. A restaurant that scores 0 to 13 violation points on this inspection, called the “initial inspection,” receives an A grade.

Re-inspection. A restaurant that does not receive an A on its initial inspection does not receive a grade until it receives a re-inspection. The re-inspection will occur at least a week after the initial inspection, giving the restaurant a chance to improve its sanitary conditions. At the end of the re-inspection the restaurant will receive a grade card. If the grade is an A, the card must be posted immediately. If the grade is a B or C, the restaurant will also receive a card that says “Grade Pending.”

The restaurant has the choice of immediately posting either the grade card or the Grade Pending card until it has a chance to be heard at the Health Department’s Administrative Tribunal.
