where are you staying?
there is a fantastic resturant in the town of alta called the shallow shaft.
If you like garlic burgers & beer, the cotton bottom is great.
rivers is a great brew pub with nice food.
market street grill for seafood (dont snicker they fly it in daily)
those are all in-between exiting 215 and getting to alta.
if you tell me where you plan to lay your head I can suggest more.
Snowbird has stepped up their dining quite a bit also.
dont miss the oher canyon.
Big cottonwood has some great skiing @ solitude & brighton as well as fine dining @ solitude.
