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.
Flowers lovers! Orto Botanico di Brera is an hidden treasure right in the center of Brera and near by Pinacoteca.
The garden is a university and museum, there they organize events and activities for the public and schools. It has an amazing collection of flowers and medicinal plants, plus little corners where you can stop by and enjoy the silence for a bit.
First we should say the flaw, Trattoria Arlati is a bit far away from the city centre and not really easy to get to with public transport. Having said that, it’s the most charming restaurant where we’ve ever been. We always go there and always get the same menu, “Risotto al Salto” and “Ossobuco alla Milanese” of course, and it’s always delicious but is not just the food. In the 60’s it was really popular among artists, in the 70’s bands started to play in the basement and now when you get in you immediately feel it. It’s a charismatic place.
