I still don't know why anybody would go to a burger joint and get chicken lol. It's like going to a mexican restaurant and getting a burger. Go to a place that specializes in chicken (Popeyes, Chik-fil-a, etc) and you'll get higher quality chicken than any burger place can churn out.
However, Wendy's ultimately has the highest quality everything on this poll. Wendy's at least tastes like real food compared to the "flavored plastic" taste BK and McDonalds put out.
