If you are looking for an “anglo-saxon” atmosphere in France, we recommend :
Fleurs de Thé , a tea room in Compiègne for a lovely “British” atmosphere (and a tasty selection of scones, cakes, puddings, crumbles, brownies, cupcakes…. yum !)
The English Shop, rue de Connétable in Chantilly. Tea room with yummy cheese cake ! A must-try !
