Here's a cool video from Buzzfeed that takes us around the world and shows us what typical breakfasts are in various countries. The video is titled What Does the World Eat for Breakfast? In the United States, as an example, the video shows us pancakes, eggs and bacon. That doesn't mean that such a meal is the favorite or most common breakfast in the USA, just that it is representative of American breakfasts.
As an American, I can confirm that pancakes, indeed, are typical breakfast fare. Or, in my case, lunch fare and dinner fare. (I loves me some pancakes!)
I guess pho is to the Vietnamese as pancakes are to me, because pho makes the video for Vietnam. Watch and see what else is served for breakfast around the globe:
