This nightclub has a great soundsystem and wonderful, diverse lineup... A lot of disco and italo... People come to dance, it has a safe space policy and its not druggy - and they have great wine and cocktails. (Yes, Im a resident there, hehe)
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.
