So I'm in Canada, and a Five Guys recently opened up near where I live. I've been a few times, and the portion sizes are always ridiculously large - my husband joke and I call them "American sizes". AFAIK all the burgers are at least 2 patties, unless you request a child's size (I think they call it a "little burger"). I usually get a hotdog, my husband gets a burger, and we split a regular french fry. There's always extra fries in the bag, so we take a few home to our dog, and throw out the rest. It's impossible for the two of us and our dog to finish a regular size fries. It seems so wasteful.
