The number of 24-hour diners across the United States has fallen by around 11%, as rising costs, staffing shortages and changing customer habits push more establishments to scale back overnight service. Despite the trend, a small number of long-standing diners are determined to preserve the round-the-clock tradition, viewing it as a core part of American diner culture rather than a purely financial calculation.

Among those bucking the trend is the Red Arrow Diner, which first opened in Manchester, New Hampshire, in 1922 and has since grown into a four-location chain in the state. Co-owners Amanda Wihby and George Lawrence say the 24-hour model helps sustain the diner's welcoming, always-open atmosphere, which they regard as an enduring piece of American heritage even as the wider industry moves away from it.
