Restaurant reviews are a bit like herding cats.  They are hard to deal with.  Just when you think they are managed another problem jumps up.  Saleh Stevens is the person to turn to if you need help with those reviews.  It is a challenge to keep a good public reputation when others control the reviews viewed by the public.  I cant imagine handing such an important aspect of my business over to someone else.  Yelp can be an example of reviews gone mad.  If you need the reviews to go away it may be advantageous to call the company directly and challenge the bad reviews.
