I also enjoyed L'Assiette Champenoise on my last trip to the Champagne region... we had a similar course to your scallop course, but it was with langoustine 3 ways on 3 different plates.... At the time, August 2006, I had thought that they were deserving of more than their 1 star Michelin ranking... they did many interesting things with products being used in a study - different sauces, cooking techniques, etc..., and had an excellent cheese cart - one of the better Pont L'Eveque I've had... Another great experience in that area is Chateau Les Crayeres in Reims... it is a wonderful place to stay, and the dining experience is out of this world... the service there was some of the best I've seen anywhere, with excellent, interesting food...
