Once rapidly growing commercial marvels, casual dining chains — sit-down restaurants where middle-class families can walk in without a reservation, order from another human and share a meal — have been in decline for most of the 21st century. Last year, TGI Fridays and Red Lobster both filed for bankruptcy. Outback and Applebee’s have closed dozens of locations. Pizza Hut locations with actual dining rooms are vanishingly rare, with hundreds closing since 2019.
