Dear …
Please let me take this opportunity to extend my thanks to you and your wife for the wonderful dinner party you hosted at your home __(on Friday/last week/etc.)__ for our team. I know that I can speak for the others when I say that it was a very enjoyable evening. The both of you are most gracious hosts. Everyone was made to feel quite comfortable in your home and the food was delicious.
Again, thank you for the invitation. It really was great to be given the opportunity to spend time visiting with both you and your wife while enjoying such an amazing meal.
Sincerely,
