My experience with the Angus Burger was unremarkable. Even though I was starving when I got to McD's, I barely ate half of it. There was nothing special about the taste. I much prefer a 1/4 lbr with cheese or the double cheeseburger.
It was so unremarkable that I cannot honestly recall anything about it that stood out. . . which puts it on par with the Burger King angus burger in my opinion.
