The 24-hour American diner is vanishing — here's what's driving the decline

Nationwide, 24-hour diners are declining, with Yelp data showing the number of such restaurants fell 11% between January 2020 and January 2025. Contributing factors include labor shortages, changes in customer behavior, and affordability concerns prompting Americans to cut back on restaurant spending. Despite this decline, some locations, like Baltimore and Key West, are experiencing increases in all-night establishments.
