I ended up with a draw the two times I tried. I made the mistake of trying a Google search I had just done previously and ended up seeing the purple links, which tipped me off to which was which. Bing was the only one that gave me local and mapped results for "Chicago Loop pizza", but Google won out just as often.

Bing is as good as Google on average. The problem is, when you're up against an entrenched competitor, good enough just isn't good enough.
