They're a US "comfort food" type restaurant - meatloaf, steaks, etc. Their aesthetic likes to hearken back to an old restaurant in the 1800s, all barn-wood panels and such. Unfortunately, they've also proven pretty discriminatory in their practices - in addition to the segregation lawsuit another commenter brought up, they had to be sued to rescind a policy disallowing LGBTQ+ workers in 1991, and there was a pretty notorious incident in 2018 where a Black bus driver got thrown out for simply ordering food at a Cracker Barrel (the staff there referred to Black people by the code phrase "Canadians"). They're also still the subject of a class-action suit for violating the Fair Labor Standards Act (in 2021), and they also keep getting embroiled in sexual harassment suits.
