As will be seen from this description, even when they were 'roughing it', life wasn't too bad for the young aristocrats of the 1920s!

Foyot's, which is no longer in existence, was a restaurant situated on the Rue de Condé in Paris' Latin Quarter. It is the setting for a humorous short story by W. Somerset Maugham, entitled The Luncheon. 

The Lotti is a luxury hotel situated on the Rue de Castiglione in Paris. It was established in 1910.
