On my way to work I like to pick up a croissant or two because at the central station there are lots of little shops that sell them in different variaties. Like plain ones, chocolate croissants, croissants with cheese and my favorites being those with punpkin seeds. The ones with sesame seeds are also great!
Toast is a close second for me.
Bagels are just unsatisfying donuts. Pancakes are great but too much work in the morning, same with waffles.
