Really nice place with amazing food and really good beer. I would recommend their super delicious homemade cakes.
We have visited Cafe Gavlan a couple of times when in Copenhagen and enjoyed it both times. The place has a nice chilled welcoming atmosphere. There are lots of lovely beers on, the staff are friendly, and the whole vibe is just nice and chilled. There are some tables outside for enjoying people watching or indoors is nice and cosy. We ate there last time and had their vegetarian burger which was very hearty, nicely cooked and filling. I would recommend you calling in for a drink if you're in the neighbourhood, to soak up the vibe and lose a few hours chatting away.
