It’s rare to find a restaurant that even pretends to focus on Native American food, but Salt Lake City has one. It’s called Navajo Hogan. It is decorated with Navajo rugs and art, and its everyday specialty is a Navajo taco — a freshly cooked fry bread topped with chili or shredded beef, beans, lettuce, and tomato. A blue corn fry bread may be substituted for the normal wheat one. On Saturdays only, Navajo Hogan makes mutton stew, which regular customers know to get early, before the night’s supply runs out. Heading north from Salt Lake City along I-15 are two detour-worthy small-town cafes: Sill’s Cafe in Layton, where the scones are exemplary, and Idle Isle in Brigham City. Idle Isle is a cordial town gathering place little-changed in the last century. Blue-plate fundamentals include divinely tender pot roast with lumpy mashed potatoes shaped like a volcano crater to hold gravy as well as such daily specials as Wednesday braised beef joints, Friday trout, and Saturday prime rib. The must-eat dessert is Idleberry pie, which is a resonating purple blend of blue, black, and boysenberries.
