The Duchess introduces the elegance of traditional London hospitality balanced with Viennese grandeur. The decor is fabulous and sets the scene for a wonderful and memorable dining experience. The building is the former KAS bank and the marble columns are beautiful. The food is a revelation and dishes arriving on the table look almost too beautiful to eat. Almost. The cuisine is a seamless blend of influences from Italy and the South of France. Other classic dishes are also on the menu, meaning that there is something for everyone. The Duchess has one Michelin star.
