I have what my therapist called "classic operant conditioning" with regards to cilantro. I will spare everyone how that came to be, the bottom line of which is that I can not tolerate it. When I am cooking something that has cilantro as an ingredient I either just omit it or add Italian parsley. While the taste is undoubtably different, I have never felt that I was missing anything. As I can't tolerate the taste of the stuff I can see no reason why I would want to substitute something to approximate it!
