Failed. Did not meet health requirements at the latest inspection. Many failures are fixed and re-inspected within days — check the inspection date.
This inspection record doesn’t carry an official letter grade — some health departments never issue one, and others (like NYC) post it after a grace period — so CleanPlate derived the status from the reported violation data. If the department posts an official grade, it replaces this automatically.
