Subway
Once the "healthy" fast-food option for folks on the go, Subway has long since fallen lower on the totem pole below other diet-friendly options. In 2016, the franchise shut down 359 more stores than it had opened. Subsequent years have seen over 2,000 Subway stores closing their doors for good.
Chili's
Similar to restaurants like Applebee's and T.G.I. Friday's struggling to stay afloat in recent years, Chili's has not been spared its fate. In 2017, the franchise's stock plummeted 40%. They attempted to introduce a loyalty program, but soon, the program began to eat into their profits rather than increasing them.
