It was a massive undertaking, so Hagendorf had to set some parameters:
He narrowed his focus to Manhattan and set simple rules: only order plain cheese pizza; only eat at places selling individual slices; and no going back after canvassing an area to catch newly opened establishments.
While Los Angeles experiences its own explosion of pizzerias, we've got a long way to go to before there's a slice pizza joint in every neighborhood.

Hagendorf reviews all the slices on his blog, Slice Harvester, and rates them on an eight-slice scale. Only one, Pizza Suprema near Penn Station, has earned a perfect score.
