I usually share my personal experiences on every restaurant I go, it doesnt matter if it is good or bad, why? because it is a good way to let people know about that place and what to expect. Also, I believe is a good way to let the owner know about the good or bad things about their service.
Sometimes when we go to any place wether is recommended by a friend or family those places are over rated and you want to have a better idea about that place.
I might not be the best to criticize the place, but I want to share my opinion with the world.
