When next in Copenhagen and you do not know where to take your lunch, I can only recommend you to visit the “Tovehallerne” close to the subway station Nørreport.
It is a bustling out-door marked with lots of food stands from where you can get excellent Danish food, but also food from many other places in the world. I normally go for the Danish simple food, not being spoiled with much Danish in Italy nor in US. This time I had some great fish cakes - really good for a hot summer day.
Another typical Danish lunch would be a few open sandwiches on ryebread and they were quite impressively decorated up high in this market - do try them, should you pass by.
Too bad that I could not being any of the cut flowers or pots of plants with me in the plane back home….
