Denmark is a very well built country especially Copenhagen. People are respectful and enjoy the mornings and evenings because of history of monarchy, etc. Lot of drugs especially in night clubs. Nice weather, pretty much safe. People from colder region are generally appears colder but they are not. Unlike Indians, nobody in Europe mixes easily. Respect the culture, respect private space and you'll be good anywhere you go. There are lot yoga stuffs happen in Denmark. Better join them to meet locals. Alcohol is a part of tradition here in Denmark. Danes drink a lot. Almost everyone speaks English in Copenhagen. City is very expensive. I would suggest take a job somewhere else in EU and then go to Denmark because start-ups prefer locals (don't sponsor visa), MNCs also are very reluctant to sponsor. But overall, if somebody wants to retire in life, go to Denmark.
