During our stay in Bologna, Italy (home of the Bolognese ragu sauce), we dined at Ristorante Bolognese twice due to its central location and menu.
Other than the well-known meat sauce, tortellini is also a featured product of Bologna. I had them in brodo (soup) and it was very comforting. Risotto with porcini mushroom smelled and tasted fantastic. We also had the reputed t-bone steak from the region (not the Bistecca Fiorentina although similar) which was extremely tender yet lean.
