Vail for a week- best of the best?
Search on Vail and the Eagle River Valley and you will get lot's of recommendations. The Magnificent 7 are Larkspur (in the Bar area), Sweet Basil (for lunch) in Vail, Splendio and Grouse Mountain Grill at the Beav, Dish and Juniper in Edwards and Avondale in Avon.
Some folks believe Kelly Liken, La Tour, Atwater in Vail and Spago (stupidly expensive) and Golden Eagle at the Beav belong in the M7.
The next tier down is very good but doesn't make the destination dining criteria for me. The ethic food here is probably not going to be as good as what you have at home.
There are a lot of apres ski, get loose and try to remember if you had a good time kind of places. Let us know if you want good times more than great food.
