The Green Parlour is located on the first floor in between the restaurant "Weinstube" and the Art-Déco-Hall. It forms part of the restaurant, but is also used for breakfast in the mornings. The pleasant and modern colour of the walls radiates calmness and, along with the dark furniture and wooden panelling, makes for cosy atmosphere. The photgraphs on the walls document historical details about Constance.
The Green Parlour is connected to the Art-Déco-Hall by large double-doors, allowing for extra space to be created for larke functions.
