Johnson explained to Bored Panda that fast food restaurants often serve as nostalgic markers of simpler and happier times. That's why so many people have fond memories of them.

"Fast-food chains are consistent and familiar, offering a sense of comfort and reliability. For many, they are linked to childhood experiences, family outings, or late-night gatherings with friends, creating emotional connections that go beyond the food itself," he said.

"It's also no accident that the brand personalities of many of these fast food restaurants are about childhood wholesomeness, which also adds to the nostalgia. Overall, the branding, atmosphere, and sensory experiences—like the smell of fries or the jingles from ads—further reinforce these memories, embedding them deeply in our minds as symbols of joy, convenience, and shared experiences."

We were curious what fast food brands can do to convince customers to come back these days if they've left due to high(er) prices. Johnson told us that though the price of the food is a critical factor, restaurants also have to focus on more than just the cost to regain customer loyalty.

"It's a major challenge. Many brands operating in this space, especially McDonald's, have attempted to go upmarket, by investing heavily in their restaurants. This provides a much-improved dining experience, but has also certain consumers who may miss its more down-to-earth, accessible feel," he told Bored Panda.

"In a landscape where many Americans are increasingly budget-conscious, value perception becomes key. Restaurants should consider offering tiered pricing options (such as Wendy's dynamic pricing), and budget-friendly meals (such as the $5 special)."

Johnson said that, ultimately, what matters is balancing affordability with value. That means "offering not just low prices, but also a compelling reason for customers to choose their brand over competitors."

He added that, "overall, the market has shifted, but these fast food chains haven't changed to address these new norms."

These days, some fast food restaurants are faring better than others. CNN reports that Taco Bell, operated by Yum! Brands (which is also responsible for KFC and Pizza Hut), is performing better than some competitors due to its cheaper food and value deals.

Meanwhile, McDonald’s, Burger King, Wendy’s, and Starbucks are all seeing less foot traffic and lower sales. They’re trying to buck the trend by introducing (more) value meals.

In a recent edition of the 'Nightcap' newsletter, CNN Business' Allison Morrow pointed out that Americans haven’t stopped going to restaurants. Instead, what’s happening is that they’re no longer willing to pay massive prices for sub-standard dining experiences.

“Many Americans are still eager to spend, they’re just not willing to pay Texas Roadhouse prices on McDonald’s food that they summon by tapping buttons on a kiosk and eat in their car. Instead, they’re going to Texas Roadhouse, where they can sit down and have some service with their meal. Or they’re swinging through Chipotle, which saw sales shoot up 11% last quarter at stores open at least a year,” Morrow writes.

It’s not just social media content creators who are so focused on nostalgia-centric content. BBC Worklife points out that marketing to people who yearn for the past can be incredibly lucrative. Many companies have jumped at the opportunity to create or relaunch products, foods, entertainment, and services that would remind people of their childhood and youth.

There’s nothing like happy memories viewed through rose-colored glasses to loosen those purse strings! (And there’s no judgment there. Many of us feel the siren call of years long gone.)

While millennials are craving things that remind them of the 1990s and early 2000s, Generation Z is already starting to yearn for the past, too.

Many people are now in a position where they can allow themselves the luxury of purchasing nostalgia-related goods. They earn enough to buy the things that either remind them of their childhoods or that they wanted to have but never could.

We don’t necessarily feel nostalgic just for our childhoods, though. Krystine Batcho, a professor at LeMoyne College in Syracuse, New York, told the BBC: “When you think about measuring nostalgia, I don’t think it’s about timing. A lot of research shows that nostalgia is very often triggered by a feeling of a difference in the present and missing something from the past, whether it was two months ago, two years ago, or 50 years ago.”
