Pasticceria Gattullo is a historic cafe located in Porta Lodovica, close to Bocconi University. The inside is like stepping back in time, as it has its original interiors.
Here you can find many delicious pastries (also some vegan options) or savouries options like panini and focaccia.
Prices depends if you sit at the table or if you stand/take away. Certainly, it's not cheap here, but the quality is very high.
