For a unique dining experience - why not eat in a laundromat? The Laundromat cafe is actually an old laundromat that has transformed into a cafe. It's actually more cafe than laundromat these days - but it is actually possible to do laundry while you eat.
When I went the place was packed with locals eating burgers and drinking beer. There are about 4 washers and a couple of dryers among the cafe. The restaurant walls are lined with great nods to laundromats in pictures and products.
Games of chess and backgammon and around 4000 books are also available to ease your laundry chores. The café serves breakfast, lunch dishes including salads, burgers, sandwiches, dinner plates, a few desserts, coffee, pastries, beer, wine, and various soft drinks.
The burger was good - but of course - it's Copenhagen, so it's expensive! But if you can get your laundry done at the same time - then maybe the time you save is worth it!
