"Locally Owned and Nationally Known ®." LG's PRIME Steakhouse in Palm Desert, California was established in 1991 by the husband and wife team of Leon and Gail Greenberg. Why do we call ourselves LG's Prime Steakhouse? Quite simply because PRIME is the best by any standard and is the USDA's highest designation for beef. PRIME steaks have the necessary marbling, that imparts a unique combination of taste and texture, which defines the ultimate steak-eating experience.
