After awful food from a brand new restaurant, I was the first person to leave a review - giving them 1 out of 5 stars.
However, the restaurant is now showing a score of 2.5 from my 1 review.
I think this and the public removal of being able to view specific feedback comments, says everything about how valid and trustworthy these scores actually are.
