Even the most unconventional tourist would never leave Milan without visiting Piazza del Duomo. Well, since you’re there you must have a traditional “aperitivo” (to get before lunch or before dinner) at the Bar Zucca where Verdi and Toscanini used to go, back from the Scala Theatre. We never sit at the nice small tables located apart, we like to enjoy our Rabarbaro Zucca standing in the crowd of the bar - just try it.
Craving proper Milanese food? Risoelatte is the answer to your prayers. Set in a cozy, 60's inspired location (complete with an original and working jukebox), Risoelatte is the perfect answer to the eternal 'what to do for Sunday lunch' questions.
I consider e/c natural wine shop a hidden treasure in Milan. Inside a building with an "Emergency" (that is actually an ONG) plaque outside, the first thing one might think is that is a hospital. Once passing the wall, there's a cute internal square, with Basilica di Sant'Eustorgio view. You can sit both inside or outside, which a strongly recommend for spring and summer days. A nice place for just passing by to grab a bottle of wine and drink it at home, having a glass of wine (they have many options) or enjoying a relaxed evening.
