Cute cafe designed by Wes Anderson at the Prada Foundation. The interior is in the style of a Milanese bar from the 1950s/60s and has a good selection of sandwiches, coffee and alcoholic drinks.

Giacomo ristorante, bistrot... They are all located on the same street, Via Pasquale Sottocorno, but the rosticceria is the more, let's say, "easy-going" (and the cheapest) of the three. It's a good place for lunch and dinner - ask for a table at the "giardino interno".

Another fun and inspiring Garden from Milano. 

Iconic pasticceria (owned by LVMH) serving beautifully crafted pastries and coffee since 1817. Don't skip on the pistachio croissant!

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.
