Diana is a restaurant that serves traditional Emilian and Bolognese dishes. For starters, they also offer tastings of single ingredients like mortadella and Parmigiano Reggiano. I tried the tortellini in brodo, which is plated directly at the table. The place is one of a kind: an elegant but old-school restaurant, with waiters rolling around the boiled-meat trolley, which I didn’t try but looked really tempting. Fun fact: at the table next to mine, two gentlemen didn’t want to miss out on a taste of tortellini after the bollito, so they split a portion as dessert.
