Fodor's Expert Review Patio Diner

A former drive-in for generations, this casual spot leans into its retro roots, with robin's-egg–blue booths and checkerboard floors—and the best burgers, shakes, and fries in town. This is also the perfect place to try Utah's famous fry sauce, made from ketchup, mayonnaise, and a few other ingredients too secret to name. While it can get very busy, the staff is always friendly, and there's a helpful sign on the wall that lights up with the estimated time your order should take.
