Many people lean on sandwiches as a healthier option in the world of fast food, and others enjoy the convenience of a good meal on the go when they're tight on time and money.
But while some of the big sandwich chains have been able to weather inflation and lingering COVID-related setbacks, like Jersey Mike's, others, like Subway and Potbelly, have faced store closures and loss of revenue.
Even though Subway is probably the most well-known sandwich chain in the world, it's never been immune to failures and losses.
Quizno's was at one point a top competitor for Subway sandwiches, but over the years ended up with minimal locations and the loss of a massive fanbase.
For a sandwich chain that considered itself the perfect "neighborhood sandwich concept," Potbelly was beginning to get overlooked by once-loyal fans.
Au Bon Pain had a booming run for a semi-small bakery chain back in the early 1980s and then again in the 2010s, offering French-style sandwiches, alongside soups, salads, and hand-crafted beverages.
Even though cousin company, Panera Bread, acquired Au Bon Pain in 2017, the chain continued to find difficulty resonating with customers.
As part of the brand's current expansion plan, the sandwich spot is transforming its restaurants into what they call the "Café of the Future," a place where customers can get in and out quickly.
