Lawry’s The Prime Rib is a fan favorite among prime rib enthusiasts looking for a delicious slab to pair with their mashed potatoes. “I used to work at a Lawry’s location and we were allowed a free meal at the time and man… getting prime rib or the roast beef with some mac and cheese and broccoli was so good,” a Reddit user said. “Even their salads. Nothing could go wrong there! They literally made the prime ribs overnight, slow cooking.” Ask to load up the potatoes for the perfect combo.
