#55: Krystal Chicken Sandwich
Krystal was founded in 1932 and became a Southern fast food staple thanks to its small square burgers, late-night menu, and inexpensive slider-style meals. Like White Castle, the chain is built more around snackable portions than big sandwiches, which affects how its chicken option fits into the category.

It ranks this low because the chicken sandwich feels more like a small menu add-on than a standout item. The size is convenient, but the chicken usually lacks the crispness, moisture, and bold seasoning that stronger chains deliver.
