I think in Le Cellier, they call the Prix Fixe menu "Chef's Choice"...at least that's what the server called it last year. Allears listings seem to match my recollection of the choices, and it lists the choices as (choose one from each category, no other choices allowed):
Appetizers
Mixed Field Greens
Canadian Cheddar Cheese Soup
Spicy Chicken and Chipotle Sausage
Entrées
King Salmon Two Ways
Salt-crusted Prime Rib
Sautéed Potato Gnocchi
All Natural Chicken Breast
Desserts
Maple Créme Brulée
Canadian Chocolate Moose
Seasonal Sorbet
If you're on the dining plan and you really want an appetizer at no extra charge, this is the way to do it. But one problem with all of the Prix Fixe menus at all of the restaurants that offer them is that the Prix Fixe menus do not include the high-end entrees...so for example, if you had your heart set on the Mushroom Filet at Le Cellier, you'll have to pay out of pocket for the appetizer because you can't get the filet on a Prix Fixe choice.
