This is a pedestrian street or zone, starting from the Leonardo da Vinci Square, through the Cathedral Square (Duomo station), and all the way to to the other end (S. Babila station).
Large and small shops were abundant but most of them only open until about 8:00pm. Seemed like the government encourage people to go home early for their suppers (perhaps the same reason in Germany and Switzerland?). Therefore, it is better to have a long walk first before try out a dinner later.
Along the pavement, there were also hawker trucks doing business, such as selling three-dimensional paintings, soft drinks and fried chestnut (I would say the taste was more or less the same as those at home).
