My husband and I are travelling to Paris for the first time from September 15-19/09. We are staying in the 7th, and are looking to make dinner reservations for restaurants in the 6th and 7th for the most part, including Chez L'Ami Jean, Fish, and Au Bon Accueil. Given the common August vacation closings, should I be trying to make those reservations in the last week of July, or should I wait until the first week of September? The first option seems too early, and the second too late. Also, am I likely to reach someone who speaks English, or should I brush up my French language skills, and hope for a sympathetic response?
