So this happened.
When the Bacon King came out, I tried it, and it was good, but it was almost too much beefy-meaty-savouryness. It needed something to cut through like, and I can't believe I'm saying it, a vegetable.
Flash forward a month or more and my wife brought me back the Angry King. This burger was glorious: you still have all the bacon and beefy goodness, but the fried onions, jalapenos and Angry Sauce gave this sandwich that acid/zingy kick. Very good. I would get this again.
