On the corner of Mass Ave. and Tremont, Mida is a reliably good Italian spot that can usually accommodate walk-ins. The $40 tasting menu (with $28 wine pairings) is a great deal considering you might get things like rohan duck breast with squash espuma (that’s a fancy word for foam) or broccoli rabe bolognese. It’s also a fun spot with a lively bar, so come here for a casual meal that’s better than a lot of places that might require reservations.
