How Los Angeles grades restaurants

Los Angeles County posts a letter placard in the window, and unlike New York the score runs the friendly way: higher is better. 90 to 100 points earns an A, 80 to 89 a B, and anything below that a C. The county inspects roughly every six months to a year depending on risk, and a failed inspection can close a kitchen until it is fixed. Because LA’s scores are final at the time of inspection — there is no pending window — a letter can be read straight off the score when the placard field is blank.
