Might be telling you something you already know but I just found a cracking McDs app. It's got a section with the nutritional value of ALL their food even the new Xmas goodies
I try and stay clear from macdonald's as I've seen the ingredients and don't have a clue what half of the chemicals are lol! But I drink a lot of their coffees and that will be useful as I usually guess the pp for a latte.
