An NYU Computer Science student found a cool way to use the Foursquare API to track NYC restaurants with multiple health code violations. Blind me with science:
If a restaurant scores 28 or more points on its graded inspection, the Health Department will continue to inspect it roughly once a month until the restaurant scores below 28 or is closed by the department for serious and persistent violations.
There are 1660 restaurants that have scored 28 or more points and have not yet been closed. Do you really want to eat at a place like that?
