Good or Bad is pure personal experience, there are all kinds of stuff that might affect your feeling about the restaurant.
I don't think it's a good exercise to criticize the reference if you got a bad experience. As long as the person don't have business relationship with the refered restaurant, I will take into consideration his/her advice. You might have different taste, requirement. But no matter good or bad, we should thanks there are so many heart-kinded person (like sage) willing to provide their pass experience to us.
