I tried cooking it once or twice but could never get used to the taste, and I like beef liver, I never noticed the difference in the two parts. I may have to try the milk trick to see if that will do it for me.
I have almost always cooked and eaten the heart though, and it was good, but found out I was over cooking it and once I adjusted my methods it is now one of my favorite dishes. I am also itching to try the shanks (osso bucco), I am told it's delicious if done right.
