Yeah, I did, they called them Holländische Friten
Anyway, they looked more like what dutch people refer to a Belgian fries, so my guess is that they're actually from Germany itself.
Anyway, I didn't have the ketchup, in cfact I opted (twice) for the danish Remboullare (or however they called it) with the dried onions. Now THAT is great stuff! Reminded me of my holidays to Iceland too, where they put the same stuff on hot dogs.
They really should introduce it down here
