I'm off to Copenhagen for a long weekend in June. All good and really looking forward to it. However I've just noticed that there is a national holiday -Constitution Day, during our stay and from what I've read this means that most workplaces and shops will be closed for the day. Could any of you lovely lot that are familiar with/live in Copenhagen or elsewhere in Denmark advise on whether these means that cafes/restaurants, museums etc are likely to be closed too and also if the public transport is likely to be on a reduced service? Any other tips and advice re; must-see's, foods to try etc would be great.
