Our story

A Historic Room for Unforgettable Meals

Two longtime friends and restaurateurs founded MTN Prime in 2016 as a place to share unforgettable meals with friends and family. The scratch kitchen pairs with rare and premium spirits and wines inside a historic mountain building that once served as the town’s grocery store.

All nice people are welcome, and all nice dogs are welcome on the patio. If it were up to us, they’d be inside too.
