Almost-always-correct store open hours are the killer app for me with Google Maps. I also love the way Street View can show you historical vision.
I find the reviews in Google Maps to be (like Yelp, TripAdvisor etc) to be thoroughly useless. Tourism-driven companies are loaded up with manipulated reviews; cafes and restaurants get ratings that often bear no resemblance to reality. The sad fact is, even where reviews are genuine, the people who leave reviews on a mainstream site like Google Maps are not a representative sampling.
