Very true, going to different places to eat is risky. Even though we are sure that it's clean based on our observation. What if our judgment was wrong? But you know, it's not easy to predict so trust our instinct. Well, I think as long as we go to a trusted place and popular there is nothing wrong with it.
Instinct helps for sure. I guess we tend to get a bit of an understanding of what's good or not, what may be dodgy, based on experiences over our lives. That's how we learn I suppose right?
