Thank-you notes for dinner are notes written to a host thanking him for a meal at his home or for one that he hosted at a restaurant. A note is required even after extending verbal appreciation.
Whether the host took the time to cook the meal, hired someone to cook it for him or hosted a meal at a restaurant, a thank-you note is an appropriate way to express appreciation for being included in the meal. A thank-you note lets the host know his hospitality was appreciated and that the guest enjoyed himself. The guest needs to send the note as soon as possible after the event, complimenting the food, company and entertainment, if applicable. A handwritten note is preferred.
