The Angus Burger basically consists of ciabatta bread, lettuce, tomatoes, red onions, mayo, mustard, real cheddar cheese and of course an angus patty. Put them altogether and you get a pretty decent burger considering it's from MacDonald's. It's quite filling too.
If you're a casual MacDonald's fan, then I recommend you try this out. If you don't normally eat MacDonald's, I wouldn't go out of my way to have this.
