A string quartet used to serenade diners here at the restaurant inside what is arguably the most famous inn in the entire National Park Service (and one of the largest log structures in the world). A pianist in the lobby has replaced the quartet, but most of the other details that make dining at Old Faithful a rustically elegant experience remain: the fireplace made from 500 tons of locally quarried rhyolite; hickory chairs and chandeliers; the soaring 76-foot-tall ceiling in the lobby; and Robert C. Reamer’s asymmetrical design, which purposefully mimics the chaos of nature. Breakfast and lunch are served buffet-style, with filling fare like corn bread, roast beef, and baked beans. Reservations are required for dinner, which can include offerings such as smoked trout ravioli or locally raised lamb.
