New York City restaurants that take online orders, and the third-party apps that deliver their food, must now include a link to the city’s online restaurant grading database or risk a $100 fine, the NYC Department of Small Business Services said in its November newsletter for food and beverage businesses.

Under the requirement, any foodservice business that accepts online orders for pickup or delivery has to include a link to the NYC Department of Health and Mental Hygiene’s ABCEats restaurant grading website, where diners can look up the letter grades the health department assigns after inspections. Third-party delivery platforms that let customers place orders for same-day pickup or delivery are also required to provide access to that grading information.

Failure to comply may result in a summons and a $100 fine, the department said.
