"A South Rim restaurant awarded a four-star Certified Green Restaurant rating for strong performance in tracking energy, water and food usage and in managing waste, reusables and disposables. Operational practices include menu-management systems and forecasting to reduce spoilage, purchasing sustainable food products, using energy- and water-conserving equipment, and selecting environmentally responsible vendors; its used cooking oil is among the restaurant-generated wastes recycled back into locomotive fuel." - Emily Hochberg
