I live somewhere in Quebec province where we have a pitifully low variety of restaurants, let alone the well-known restaurant chains. All I can find within 10 minutes to 5 hours of driving is a decent amount of Subways, a handful of McDonald's and the lone A&W. Well, that's what I get for living a less-populated region far removed from my province's capital.
Speaking of McDonald's, my nearest fast-food restaurant does a respectable job of delivering food pretty quickly with acceptable quality. I emphasize "acceptable", since they don't taste anywhere near disgusting, but aren't excellent either. Though, I do absolutely recommend McFries, McPoutine (available only in Canada), and McFlurries with M&M.
I honestly don't exactly know much about the McDonald's situation in USA in general when it comes to food tastes and the quality of service, but I know for sure that there are some McDonald's that handle their jobs better than others. I'm aware that their Canadian branch receive ingredients from different suppliers, and that they're adhering to the stricter food safety regulations and public health laws.
