For documentary reasons, I take a photograph of every hotdog that I buy at a pølsevogn. The composition is usually such that the hotdog is in the foreground while what there might be of scenery, attractions or points of interest are in the background, way out of focus. This has resulted in a (very small, but slowly growing) album of photos that is presented elegantly below. But first: A customary side note on what you should order at a pølsevogn/sausage stand in Denmark.
Danish hotdogs are (in my opinion as with everything else on this site) best enjoyed as a "ristet hotdog uden rå løg", i.e. a fried (not boiled, please) hotdog sausage in a hotdog bun with ketchup, mustard, remoulade, fried onions, and pickled cucumber.
This was the best tasting hotdog among the ones photographed
