I'll be in Lille, France for a week or so starting in a few days. What are some good restaurants that are preferably around 10-20 euros per meal, i.e. maybe Aux Moules?

FLUNCH cafeterais are about 10 euros I believe and you get unlimited helpings of everything IME that is not meat - you get one serving of meat but unlimited veggies, non-alcoholic beverages (wine is cheap too) - downhome French food - FLUNCH has zillions of outlets all over France and a favorite for years of my French friends and many French in general.

I always have a meal at Aux Moules every time I am in Lille, which is at least two or three times a year.

I have also eaten well at Les 3 Brasseurs across from the Lille Flandres station. '3 Brasseurs' is a chain, but it does reliable regional and standard French dishes.

My last meal in Lille was with my brother and sister-in-law a few months ago. We were getting the train back to Paris from Lille-Europe and didn't have much time, so we just ducked into the Euralille shopping mall between the two train stations. The brasserie just inside the door on ground level coming from Lille-Europe provided an exceptional meal and also the cheapest meal we had.

Is it really possible to eat at any proper restaurant for 10 euros? Or even 20 euros? With du vin?

Eh, no wine, just main course. I'm not looking for formality either.

I would recommend Les Trois Brasseurs too. Big choice, excellent food at a very decent price.
Their "Assiette gourmande des Trois Brasseurs", at 15.50 €, is absolutely delicious.

The menu has increased since this June, when the basic menu was 13€. I suspect that one can find similar meals in Lille.
