Here is the iPhone app that lets you see (iTunes link) the Department of Health sanitation ratings around you, or in your neighborhood, or by name. The City, in announcing their app, very carefully suggests some data in praise of the grades — salmonella is down! Eating out is up! — but doesn’t go so far as to suggest causation. As you can’t. But yay! Total information awareness nannystate! FEAR THE B GRADES, ALL THOSE EGGS ARE SLIGHTLY WARM.
