La Pépite on Place Sébastopol in Lille is a bar canteen of five euro bowls, the cornflake-crusted fried chicken among them, open late at weekends.
Why locals love it: Five euro bowls that change every week, voted the best bar for a snack by the readers of a Lille city guide.
Tip: Every bowl costs five euros and the list changes weekly, so ask what is on rather than reading an old menu.

Costaud on Place du Vieux Marché aux Chevaux in Lille builds sandwiches to order by day and turns to shared plates at night, across three floors.
Why locals love it: Three floors of a 19th-century building on a small square off the main Vieux-Lille circuit, sandwiches by day and shared plates at night.
Tip: The square it sits on is one street off the tourist route, which is why it stays a local room.

Smokey Banh Mi on Avenue du Peuple Belge in Lille smokes its own meat and buys its bread from the Degruson bakery up the road in Vieux-Lille.
Why locals love it: Meat smoked on the premises and bread bought from the Degruson bakery up the road, which is why an 11.50 euro sandwich has a following.
Tip: Ask what has been in the smoker that day. The pork is the constant, the rest rotates.

Chez la Vieille on Rue de Gand in Lille is the maroilles house of the strip, a cluttered estaminet where the cheese turns up in almost every course.

Tip: Reservations are essential in the evening. The room fills with regulars before the visitors arrive.

Au Vieux de la Vieille spills onto the cobbles of Rue des Vieux Murs in Lille, the terrace estaminet locals send visitors to for carbonade and welsh.
Why locals love it: It sits on the tiny Place aux Oignons rather than the main circuit, which keeps the terrace calm on a busy Saturday.
Tip: Take the terrace on Place aux Oignons rather than a table inside. It is the quieter side.
