stimpy,
if you want a good steak chain in France, go to L'entrecote. Allright the menu is not diverse, but honestly their entrecote with the peper sauce is AMAZING! I am just salivating thinking that in a couple days i'll go and enjoy it!
Also i can think of a lot of midrange chain restaurants in France, Hippopotamus is one of them (personally i don't mind it)
Buffalo Grill (decent restaurant, not great but decent)
Le Bistro Romain (overpriced imo except to eat the unlimmited carpaccio of beek)
Courte Paille
and i almost forgot one of the most famous Leon de Bruxelles (moules et frites)
etc...
