Excellent review of Le Cottage. It has always been a great restaurant and happy to hear it continues the same great food and service under the new operators. As for 'the tip',15% is automatically included on all cafe and restaurant bills, and on the prices listed on menus throughout France. Therefore the custom is to leave only a small additional tip if one wishes, usually no more than some loose change, and up to perhaps a maximum of 5% if one is truly pleased with the service. It is called a "pourboire" and should be enough to cover the cost of a drink for the server.
