I was there recently for an informal aperitif with some friends.
I was pleasantly surprised by the location of this bistro: a sort of hangar full of plants, with a refreshment area inside. Beautiful from an aesthetic point of view.
Then, on the food side, there is really an embarrassment of choice with an aperitif formula that for 16 euros offers a drink and a series of appetizers (with vegan, gluten free and lactose free options) that are worth a mini dinner. The pastries also seemed really good, but I didn't have the chance to try them.
Definitely a hidden gem in that area, I will definitely go back!
EDIT: I had the chance to have brunch there and I confirm my impression. 10/10, a rich and filling dish and a crazy price for being in Milan!
