It's Restaurant Week and Washingtonians are making the most out of their fancy meals on a dime, but if D.C. Councilmember Mary Cheh has her way, diners might get more information than they bargained for. This week, Cheh introduced a bill, for the second time, that would require the D.C. Department of Health to issue a letter grade to a restaurant based on its health inspection and for that restaurant to display the grade prominently in its front window. The Restaurant Hygiene Transparency Act, as Cheh's measure would be called, follows similar efforts in Los Angeles, St. Louis and New York City.
