I believe their Patty's are all 100% beef? Or am I mistaken? I've heard their chicken is also of highest quality. A friend of mine did a Consulting job at the chicken provider for mcd in my country and said mcd gets too quality batch first, then the big supermarkets get whatever is left.  

 From what I understand the McDonald’s menu varies by country. I would not be surprised if you are outside of the USA and getting better quality meats than us. 

 Actually, I learned that mcd has 100% beef from @saifedean (who resides in the US from what I know?) 

He told me he sometimes goes to mcd and orders a stack of Patty's for a full fledged carnivore meal 😁 

 Hmmmm maybe, I’d be surprised though
