The best and one of the oldest restaurant in town to get the traditional danish open face sandwich. Unbeatable!!

Contemporary Art Gallery in the center of Copenhagen focusing on mainly international, abstract, minimalistic art. 

Trekroner fort is is a wonderful place, 15 minutes by boat from the city centre. The old fort is open to the public during the day, but only accessible from the water side. The current area was founded in 1786, but was not finished at the Battle of the Nest (April 2, 1801) or at the British bombardment in 1807. It was not until 1828 that construction was completed after a period of economic decline. Photo: © Ture Andersen

As the summer is my favorite time of the year and that the beach is just 15 min bikeride away, I recommend Amager strand. Full of people usually though, but even so it gives a bit of an exotic touch to such a scandinavian city with the sea and the bright sand in the hot summer days.

The actual canteen of the Kunsthal Charlottenborg gallery, It has only one dish a day, changing daily. Led by chef Frederik Bille Brahe. Great food and atmosphere.
