If you are up for something more special and adequate for a gurmet palate, I would like to recommend this restaurant which I had the pleasure of visiting during my last trip to Bologna. Ristorante Burani is not located in the city centre, and you need a car to get to the place. The location is Pieve di Cento, about 40 minutes drive from the city centre.
This restaurant has been awarded "1 fork" (on a scale of 1 to 3) by "gambero rosso", which is a very significant award within the Italian culinary scene.
As in any respectable Italian restaurant, you will be served a selection of bread specially prepared by the chef. The bread was of good quality, although not absolutely the best.
This 'zuppa di carciofi con crostini' (artichokes soup with crostini) was served for 'free'. Although I am not a big fan of artichokes, I could enjoy this thick soup because of its mild flavour. The bits of crunchy bread could either be enjoyed with their crispness or soaked into the soup.
