@foxnews: The 24-hour American diner is slowly disappearing. The number of U.S. restaurants serving customers around the clock fell 11% between 2020 and 2025. In Los Angeles alone, nearly 3 in 10 all-night restaurants disappeared. Labor shortages, elevated costs and changing customer habits are all squeezing the late-night tradition, with fewer younger Americans drinking and affordability concerns pushing diners to cut back on eating out. But one century-old New Hampshire diner is bucking the trend. Red Arrow Diner has all four of its locations back to 24/7 service, keeping the griddle hot for first responders, third-shift workers, travelers and the after-hours crowd. "There is a seat for everybody at the counter," co-owner Amanda Wihby says. "And what's more American than that?"
