I hope that your sister finds something on the menu she can eat. Le Cellier is wonderful. I am pretty picky and have always had a good meal here. I have enjoyed the prime rib and they have a fantastic caesar salad. If there is something I am not sure about, I have asked to have it on the side and have always been accomodated mostly sauces and substituted sides).
I can't wait for December 6th, that is when we have PS. I have been looking forward to this birthday dinner for a long time now!
