I just got back from over a week in Vail and have a lot to report. First the good:
Larkspur -- Every course was great and the room was the nicest we saw. Terrific mushroom soup, roasted chicken with flavorful skin that stayed crispy to the last bite, and a smooth cappuccino pot de creme. The service was a little bit of a disappointment. Our waitress seemed to be training someone new and appeared to enjoy scolding her in the middle of the dining room.
Sapphire -- The entrees were the standout here. The rack of lamb was very nicely cooked although it could have been trimmed better. The prices were surprising since people told us that it was less expensive than Larkspur or Wildflower.
Alpenrose -- Desserts were the highlight.
Wildflower -- The best service of everywhere we ate and all of the food was pretty enjoyable.
Bart and Yeti's -- Tasty burgers.
In order from best to worst, we were less crazy about Vendetta's, Blu's, Pazzo's, Los Amigos and Flying Burrito. Los Amigos was actually shocking since several locals told us to go there "for great Mexican."
Thanks to everyone for the recommendations.
