I feel like it depends what you mean by avoid. Most of the people answering it here seem to be saying "NEVER, NOT IF IT WERE THE LAST FOOD ESTABLISHMENT ON EARTH GROSS GROSS GROSS".
And like, I'm not that way. I would say like in general I don't eat fast food like...more than maybe five times a year? And usually when I do it is McDonalds.
And I do avoid it in the classic sense of the word because it is unhealthy. But I don't like, never ever eat it. I just almost nearly never ever eat it.
I like their food tho. I have to admit their quality of food really fluctuates based on place. The one we have in the ritzyish area where I live is super good compared to the one on the wrong side of the tracks. Don't know if anyone else notices stuff like that?
