Admittedly, it's after the fact, but other than a very nice personal note of thanks and a large tip for the gracious service, what should we have done in this situation? It was my son's 21 birthday. He had been dreaming about a particular dish that he used to get in two restaurants that had closed down years ago. We recently learned where the chef from those two restaurants has been working. We contacted the restaurant and requested that the chef prepare that special dish for our son. When we appeared for dinner (two adults and 3 21year olds), the chef came out to say hello. The great wait staff when presenting the menus advised us of the special dish which my son obviously ordered. After the apps and mains, the chef sent out three desserts gratis and they made a big production over my son at the presentation of same. The chef reappeared to touch base with us and chat briefly. We thanked him profusely and complimented him on the food. Had we ordered wine, I would have certainly sent a glass back to the chef; but no one but myself wanted any; so a glass was all I had. We later learned that the chef came in on his day off to prepare this dish for our son. Although this restaurant is located in the next town from us (approx. an hour away), we most certainly will return. But the nagging question remains, what should we have done to show our appreciation for what the chef did for our son that helped make it a memorable dinner?
