Tillster’s 2026 Phygital Index Report reveals that 45% of U.S. consumers say their favorite restaurant chain has changed in the past year, signaling a sharp decline in diner loyalty. The report highlights that diners are prioritizing food quality, convenience, and speed over price, leading to a shift away from traditional fast-food and fast-casual chains toward convenience and grocery stores, and emphasizing the need for restaurants to focus on seamless, personalized experiences rather than discounting to retain customers.
