I believe in ignorance is bliss when it comes to the food I eat, especially those that I usually have. I don't know why, but when I taste something really good, my brain takes a special note of it. So if I eat the same dish but is of lesser quality, I don't appreciate is as much, even if it is still good. So if there is a type of dish that I frequently eat, I try to avoid trying them in places where I can't easily go.
