Trattoria di Via Serra in Bologna's Bolognina is the Flavio Fabbri and Tommaso Trifoni room, a 28-seat osteria with the city's most-cited tagliatelle al ragu.
Why locals love it: Bolognina's quiet, neighbourhood-scaled trattoria; the tagliatelle al ragu is the city's most-cited by editors but tourists never wander north of the station.
Tip: Book three weeks ahead online; lunch is the easier seating and the kitchen runs the same carte at both meals.
Address: Via Luigi Serra 9/B, 40129 Bologna BO
Why locals love it: Mazzini's no-website neighbourhood osteria with the fixed-price set carte; locals fill the dining room and the tourist guides miss it.
Tip: Book by phone two days ahead; the 25-euro set carte runs at lunch only and is the value play.
Why locals love it: Sfoglina counter with hand-rolled pasta sold by weight; the dine-in carte takes walk-ins for the same pasta the restaurant kitchens cook.
Tip: Walk-in for the dine-in until 14:00; take-away pasta runs from 5 euros per 250g and the queue thins after 11:30.
Why locals love it: 1465-founded wine-only osteria where regulars bring food from the surrounding salumerie; the city's oldest tavern, never on a tourist guide.
Tip: Cash only. Bring food from Tamburini or Paolo Atti; the osteria sells only wine. Closed Sunday.
Why locals love it: Saragozza's family trattoria on Via Andrea Costa, well outside the tourist orbit; the Bolognese carte for the weekday lunch crowd.
Tip: Book by phone two days ahead; the 40-seat room runs the same carte at both meals and the lunch is the easier seating.
Why locals love it: At the foot of the 666-arch portico up to San Luca; the post-Sunday-walk lunch destination that requires a 25-minute portico stroll first.
Tip: Book a week ahead for Sunday lunch; the portico walk from Porta Saragozza is the traditional pre-lunch passeggiata.
Why locals love it: Andrea Liguori's Sicily-and-Emilia natural-wine bar with a 30-seat room; locals queue but tourists rarely find Via Valdonica.
Tip: Book three days ahead for the seated dinner; bar standing-aperitivo runs 19:00 to 21:00 walk-in. Closed Monday.
