Feeding hungry teenagers in Paris

[Cuddleczar]

We are going to Paris for three days later this week and me and DP have not been there together for more than 20 years; now with 3 DDs, aged 15, 17 and 19, I'm aware that we need to schedule food stops. Must avoid the walking-around-for-one-hour-to-find-somewhere-to-eat syndrome. Breakfast not a problem, but has anyone got suggestions for lunch and dinner? When you just need something warm and filling and not too expensive? I remember when we went before we went to "selfs" ie self-service cafes that did very reasonable hot food (and sandwiches). A bit like the chain Casino, though I'm not sure they have those in Paris. So are there any chains that spring to mind, that are good value?

I know one chain called Flunch. They do proper meals, dish of the day deals etc.

As a quick alternative, Boulangeries Paul (also a chain) do amazing baguettes, pastries etc. The ones I've seen have seating areas so you can eat in if you want.

The large department stores all have restaurants, If you are in the area Printemps and Galeries Lafayette on Bld Haussmann have restaurants with panoramic views, Printemps would be the cheaper.
I don't think you will starve in Paris, have a wonderful time!!

Hippo does big burgers etc that are quite good value.

The food court under the Louvre is cheap - the chicken place and the crepes are fab

Mc Donalds next to the Louvre.

We had an apartment, so on the second night we got a huge Chinese takeaway. Cooked the rest of the time.

Thank you everyone, that's really helpful!
