Hmm... Hard to choose. McDonalds makes miniature portions that are supposed to feed us, but the food tastes good. I've never been to Burger King, so my vote goes to McDonalds.
I've tried both and..... they are both horrible in my opinion. If I had to choose one then I would say Burger King. McDonalds has small portions and I just don't like them. But like I said, they are both horrible in my opinion.
Those are very sacred foods meant only for AWESOME Americans like myself. Perhaps you might get a chance to have some, maybe, if you ask nice enough... Canada isn't so far away after all. Let me speak to them, and see if we can arrange for a meal to be sent to your house.
