"'I usually go to Ciro's.' 'Why not Paillard's?'"

Ciro's restaurant was situated on the ground floor of the Hotel Daunou in the Rue Daunou in Paris. A highly fashionable eating place, it was one of a chain of restaurants with the same name, branches of which could be found in Monte Carlo and Biarritz.

There is reference on the internet to Paillard's being a highly respected restaurant in Paris in the early years of the 20th Century, but information about its location, origins and subsequent history is sparse.

Does anyone have more information?
