I know it's a very arty way of writing, but could it not get to the point? What is a pizza farm?
Yes it is obviously a farm that sells pizza, but doesn't that begin to pose follow up questions for you? It is a pretty incongruous scene. Farms rear animals, grow crops and generally trade wholesale. They are also pretty remote.
And while lots of large farms are miles from anywhere, many farms are only a few minutes outside of major cities - commuting farms (or more and more, work from home farms).
