High end restaurant near or in Park City for Friday!
I've always heard the very best things about this and it's my goal to try it. I'm sorry I can't speak about it first hand.
I've also heard things about the Mariposa, as was suggested.
Stay away from the J&G Grill at the St. Regis. I've tried it twice and it just isn't up to it's reputation.
Have fun in PC!
