If your answer is yes, then you are in luck. Just head to the main train station in Dortmund and look for for the Waffel am Stiel (literally means "waffle on a stick") stand right past track 7.
Here, for a mere 60 cents, you can get a deliciously warm waffle with powder sugar on a stick. They're available with a chocolate shell as well, but for some reason that doesn't seem as delicious, so I've never tried it. They're also the perfect size so you feel like you've got enough to enjoy, but not so much that you feel like you shouldn't eat again for a week or anything. It's basically pure happiness to go.
I mean really, for only 60 cents, how can you say no? I'm not going to lie, they've become a pretty standard part of my trips to the main train station.
