McDonald's is putting $8.5 billion behind a sweeping plan to modernize its restaurants, upgrade technology and support franchisees through 2036. The makeover will include redesigned restaurants, simpler operations and expanded use of generative AI technology to help make locations more efficient. The fast-food giant is also looking to appeal to changing tastes with more protein-focused options, including grilled chicken, egg bites and protein bowls, as it works to bring customers back. #mcdonalds #restaurant #food #news #usa
