While small in size [if you don't count Greenland], Denmark has 7000 km of coastline and much of that is beach. In the summer the beaches around Copenhagen are filled to overflowing with tens of thousands enjoying the heat.
So why not start a sushi bicycle service to roll down the paths at Amager Strandpark, selling delicious sushi to the beachgoers? A custom three-wheeler cargo bike with refridgerated box, bringing the fish to the beach.
Fishing was never this easy. Classic Copenhagen.
To see what the bicycle parking looks like at this beach, we have this post from last year right here.
