Chefs de France doesn't serve Macaroni and Cheese. The menu lists this: Gratin de Macaroni - Baked macaroni with cream and gruyere cheese. This is exactly what you get when you order it. Noodles baked in cream sauce, covered with a gratin of gruyere cheese. Perhaps the restaurant should put a disclaimer:
This is Not Macaroni & Cheese.

It seems odd to criticize a restaurant for serving an item exactly as it is described in the menu just because you thought you were going to get something different.
By definition, gratin is something very different than cheese sauce.
Here's the American Heritage Dictionary definition:
gra·tin (grät'n, grāt'n, grā-tāɴ') Pronunciation Key
n. A top crust consisting of browned crumbs and butter, often with grated cheese.
[French, from obsolete grater, to scratch, scrape, from Old French; see grate1.]
BTW Kevin, I enjoy your articles on Micechat. Does the new DVC policy of replacing real dishes in studio villas with foam cups and plastic glasses qualify as "Declining by Degrees"? I think so.
