I almost don't want to write this review so that this place stays a hidden gem, but they deserve the praise.
Intermezzo is open late. The service is great and friendly (but not hovering). The food is amazing, especially the Serbian section. Try the:
Steak sandwich
Sarma
Burek
Piroska
The restaurant is quiet and cozy, with a big patio if you want to sit outside. Did I mention that they always have great music playing? What more could you want?
