Wow man, now you're talking! My mouth is watering right now. Now that op has mentioned it, I'll probably have pizza with mushrooms for lunch tomorrow!

I don't think the OP is saying, "don't eat burgers/fries/pizza/whatever because it'll make you fat!" I think he is saying not to eat at the chains because the food they make there is lesser quality than what you would find at a local, independantly run restaurant making the same type of foods. Which I could understand and agree with. However, say what you will about it, I love me some Pizza Hut, Dominos, McDonald's, etc. And not only do I enjoy eating at these places, it's more affordable, faster, and often more accessible than locally owned/run places.
This thread is being taken for saying a point it's not. It's not against unhealthy food; I'm against fast food restaurants when you can get unhealthy food at tastier places with some nutrition! Support local businesses and stop eating chemicals.
