I can not speak for a bacon sundae, but I will say this - Lenny excluded of course - if you ever have a change to have chocolate covered bacon, have it. I call it "pigs in mud" personally and I make it quite often. Whenever I make chocolate covered strawberries for my wife, I always cook up some bacon to make for me.
I can see where this will be really good, but at over 500 calories per serving, I don't see me eating it any time soon.
