On Sunday I went for a spontaneous lunch with my family. We had picked "Um Haeffchen", which serves salads and in particular fondues, tartiflette and flammkuchen. I had the salade norvégienne (pictured), while my sister ordered the tarte flambée.
The food was really good and so was the service but we had to wait quite a while for our meals to be served, about an hour. I would eat at Um Haeffchen again though, especially during the upcoming autumn and winter months. A nice cheese fondue or tarte flambée will be perfect at that time.
