@1nter4ri I don't know. I haven't been to a Mc Ds for years, since they stopped chips and gravy.
From my recollection of Mc Ds when I visited the US in the 90s there were some stark difference apart from the key items Big Mack etc. I remember there being two types in the US one that had the mascot Speedie.
I'm having Chicken Big Mick's tonight and it's nearly dinner time
