Saddle Peak Lodge
I envy you. You will have a great meal and, although I haven't eaten the entire menu under the relatively recent new chef's supervision, I doubt there is anything that you need to avoid.
Since game dishes are relatively rare in most restaurants around town, I'd suggest you go in that direction. Elk is wonderful; like filet mignon but with flavor! If that's on the menu, do consider ordering it.
Happy New Year!
