Yes, "Two Mandarins", for Deux Magots. Happy Travels!

Les Editeurs is good but I wouldn't call it historic. It is decorated with literary memorabilia and books but there was Alsatian restaurant on the site until about 10-12 years ago.

Splendid and useful feedback, my friends! Will be in Paris in mid-October for 4 days, so will try to visit least 12 of these. Much thanks to all for taking the time to respond and reinforce why this Fodors forum is so lively and helfpul. Cheers!
