Tiny wine bar and store in Milan's Chinatown area, selling wine by the bottle and by the glass, alongside small plates/snacks. Friendly staff and great selection of wine. Always popular so be prepared to stand!
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.
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.
To really reach/understand a city you must live there or, at least, acting like you do. Nothing makes you feel more like a Milanese D.O.C. than stopping by Frida's on a Sunday morning to buy some flowers. Located in Brera this tiny shop has an extraordinary colour palette of flowers and plants. After that we just take a walk in the neighbourhood holding our bunch of Brassica Oleracea and our day is made.
