Milan’s 40 30 30 has been the first bistro dedicated to the Zone Diet in Italy. Rigorous materials in sober colours are expressed in a contemporary language, making the space welcoming and functional. Milanese architecture is a continuous reference: terracotta and granite walls and floors, combined with wood, textile fibres and marble. The bistro is divided into three areas, three ways to consume food. One is characterized by a large counter in marble and black terrazzo, a focal point of the entire area. Another part of the room is a traditional venue for diners. On the lower ground, customers enjoy the chef’s specials, while sitting at a large, shared table with direct views in the kitchen.
