I would like to mention that I have read through ALL the threads about restaurants mentioned in the Paris Digest thread. And a few not mentioned too.
Most of them are a little old and the food scene could/would have changed.

Now to my questions :

I am looking for a few suggestion for good quality bistros/restaurants in Paris.

Mostly I am interested in restaurants with good lunch deals.
Partly because I find it an economical way of trying good restaurants and partly because I am staying in a hotel with a exec lounge, so I probably won't be interested in a big dinner.

As part of my stay is on the weekend, I am also interested in restaurants that are open on the weekend.

I am not very concerned about ambience, fancy decor, and attentive waiters but I am very interested in good and interesting food.
I am not thinking of Michelin starred restaurants (did that last time).
The price range is flexible.

I have also been checking the internet and there are just too many options, I have a problem narrowing it down and choosing.

To give a few examples of what I, from my searches, see as possibilities :
Les Bouquinistes
Atelier Maitre Albert
Allard
Au Comptoir du Relais
Le Grand Bistro (chain of 4 restaurants)

These are probably on the high end of my price range and I wouldn't mind a few suggestions for some cheaper options.

Thank you very much
