Where to hang out in Milan? :)

What are the common hang out places in Milan when you are a student in Accademia del Lusso? The institution is located in the heart of Milan which is a really cool spot for students to catch up. The location is really convenient and reachable by public transport, too. Where do students usually spend their free time and meet each other after the classes? It would be great if you guys can share your experiences !!! :sunny: :smile:
