Palmenhaus is absolutely gorgeous. Although it was warm enough to eat on the terras, we prefered sitting inside to enjoy the beautiful greenhouse with the plants. Absolutely a top location to have lunch. I had asparagus with salmon and my boyfriend chose a Wiener Schnitzel. Food was ok, but nothing special. The food arrived rather quickly which made me think it was just heated. Service was friendly and correct.
