It's 100% a facebook review system, not tied with Google at all. You should see reviews (and who left them) if they left a comment with it, if not then I don't believe you have anyway to view who left them.
They are public to the friends of who left them however.

I tried removing my street address but not the city, state and zip code and it did not remove the rating on the home page. Do you think it takes awhile to populate?
