I had to do it. It was 2AM. I was a bit inebriated. I was very hungry. It was open: I entered, ordered, and I ate. Wow, what a cheeseburger.
It's been over five years since I have eaten at a McDonald's. So I am not sure if it was due to my state of mind, my hunger level, or the beef here in Uruguay, but it was one of the best cheeseburgers I have ever eaten.
