Since 1949, the House of Prime Rib, one of San Francisco’s most legendary and perpetually packed restaurants, has done one thing, and done it very, very well. Giant prime ribs are rolled (yes, rolled) to your table and carved to your specifications, and served with salad, mashed or baked potato, creamed spinach, and a Yorkshire pudding. And that’s it. Sure, there’s a token fish dish, but you come here for the prime rib and the dessert cart or you don’t come at all. The owners have known that all along, and have wisely decided to leave the menu untouched.
