I guess it depends on whether you want to stay IN BC...
With a short drive, you can get to many of our local spots.
In Edwards, the Gashouse(BBQ/American food) is a casual, relaxed atmosphere. Very good food and I think, reasonably priced.
In Minturn, one of my favorites is Chilly Willy's, for TEX-MEX. Fajitas to die for, and great Flavoritas! Behind CW's is the Minturn CC, where you cook your own steaks and seafood. Across the street from CW's is the Saloon (mexican) with very good Margaritas.
If you are in Vail, Bart and Yeti's (Lionshead) has arguably the best burgers in town. Good ribs, stews etc, too. DJ's(Lionshead) is THE place for breakfasts! (cash only) Billy's Island Grill is very good steaks and seafood in a relaxed setting.
In Vail Village, The Red Lion is great, and Los Amigos is quite good!
I think at any of these places, you will find something for even the most diverse group of diners!
