For local nightlife Versteboro or the City Centre. ( the latter more upscale options and the former if you're younger). You'll find Copenhagen is mostly a city of small cocktail bars. You can't go wrong with most of them listed in any 'best of' guide.

Tivoli Foodhall or Westmarket are both interesting takes on street food for a moderately priced meals.
Some favourite mid-priced "Danishy"restaurants are Pony in Vesterboro. Restraurant Gorilla, Marv & Ben's or Host closer to city centre.
If you feel like breaking the bank, you might get a last minute spot at the "New Norma" (although I personally prefer 108 or the Kong Hans in that range)
