I first read about the grill in Sunset magazine several years ago and finally made a trip there this summer. The owners earned their cooking experience in the kitchens of back-country outfitters and learned the hard way how to cook gourmet in a rugged setting. You can get more info on their website (below) but I will tell you that the restaurant is worth a special trip. As if the plethora of national parks and monuments in the area were not enough of an attraction, you can have a locally grown, contemplatively prepared, organic, tasty meal somewhere along your journey. They serve breakfast and dinner only so plan accordingly.
