this is my take. the thought of eating chicken out of any restaurant totally grosses me out. (chicken issues).
i don't mind eating meat in small portions, but would be perfectly happy mostly vegetarian.
i have tried the Quorn brand subsitute chicken patties, and i think they are great. i really like most of the Quorn brand offerings.
OTOH, KFC really grosses me out. last time i went in one of those, it was a combo kfc and a skippers. waves of fried grease assaulted my nose walking in. blech
probably a pass for me.
