Too bad our uppity mayor is too short and too non-Mormon to ever fly as pres. Despite some restaurateurs’ laments, he has been good for food. The latest move is allowing city agencies to buy local. Given that NYC is the second-largest institutional buyer in the country, after the military, that could be very, very good for upstate farmers. And even for Brooklyn/Queens artisans who are thinking out of the crate. Sixteen-ounce mayonnaise? Bring it on.
