World famous burger/beer joint. Try a schooner (I have to drink it two fisted) and a caribou burger (not on the menu). Put some quarters in the jukebox and play a round of pool.
Wander the village, tour the hallways with b&w archive photos of famous past guests, and finish off a Sun Valley date of outdoor iceskating or bowling with a nightcap at the Dutchen Room.
Cozy, great food, and only a short walk away
