Christmas Day Brunch in Vail/Beaver Creek (CO) area

Our all-adult group of 6 is looking for the BEST Christmas Day BRUNCH (i.e., 11am - 3pm) in Vail/Beaver Creek, Colorado or surrounding area (we are staying in Dillon). I think Aspen is too far to drive.

Cost is no object, we are simply looking for the best (food is most important, service second, view/ambiance third).

Our main preference would be a Brunch Buffet, but we could also do a menu as long as they also have breakfast type items on it.

I have done significant internet research but am finding that most of the nicer restaurants don't have anything special going on and/or aren't serving Brunch (just their basic lunch menu and/or a special Dinner menu starting later in the day).

We have reservations at the new Atwater on Gore Creek (but since it's opening this week am obviously not going on reviews but reputation of the group behind it). Thus, we are looking for more options.

Any help is much appreciated.
