Now on to food and drinks, Milan is the birthplace of my favorite time of the day - aperitivo. Drinks with a (cold) food buffet in cafes.
If the city seems not enough for you, you can take a day trip to Lake Como. To be honest, I almost prefer to spend my day there after a nice late breakfast and return for aperitivo time to the center. Here you can find our how to reach Lake Como from Milan's center. It's worth it, look how beautiful. Plus you may run into George Clooney.
Have a great day!
