Just 25 min by train from downtown Copenhagen lies an old and beautiful forest and country area inhabited by wild (but friendly) deer. It's a vast, mysterious space for getting lost in and perfect for spacing out on mushrooms if you bring friends. Stay away on Sundays as it fills up with screaming children and zombie parents. Grab an ice cream on your way back at Bakken, the old David Lynch-ish fairground located at the outskirts of the forest.
A Kilometer stone (circa 1925) stands directly outside Nørreport station, in Copenhagen K. It's easy to pass by, but definitely worth noting if you're in the area — The typographic work on it is incredible.
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.
Sometimes it is great to look at surreal looking things to set the imagination going. This is an slightly old-school museum with traditional ways of presenting the wast collection, but I personally like that. This museum is a part of the Natural History Museum of Denmark, and has a permanent exhibition ‘From pole to pole' which show animals from around the world. The collection manifests that there is so much to know about the world and who we share it with, and it really sets your mind working. Get inspired by geometric patterns on seashells, colours of birds or scales of reptilians. The museum has many important remains of recently extinct birds in storage, including the eyes and internal organs of the last two great auks, several specimens of the pied raven, and one of only two known complete skulls of the dods that were taken to Europe in the 17th century.
