Any Given Sunday's: 365 days of American football. I feel that its focus should be on football's less expensive incarnations - junior high, high school and college through Division I-AA. Anything above that costs too much to license. I suppose you could probably get like local semi-pro teams, too.
Flannery O'Monday's: This, I think, would be the most successful - a Southern gothic restaurant chain! Lots of the mid-century South decor, but it would encourage diners to return because there would be an ongoing narrative that is constructed by the waitstaff, which could be harvested from community theater programs. The narrative would be consistent across all restaurants and writing this ongoing play would be a great job for English PhDs who studied O'Connor or Faulkner! Could also pair up with 7th or 8th grade English classes that are reading To Kill A Mockingbird.
Judge Wednesday's: A legal theme. I've been to restaurant/bars with legal themes ("The Court" was in an old courthouse. It works.
Doc Thursday's: No one has fused folksy old-timey medicine with casual dining. No one. On the wall would be unusual medical instruments, pictures of sick people and your waiter would wear suspenders and one of those things on their head and a stethoscope around their neck.
Saturday Evening Post's: What screams "nostalgia!" louder than the Saturday Evening Post? Nothing. That's why it would be a good cross-branding opportunity for casual dining restaurants. (They have a website?) It wouldn't have things like chipotle-wasabi ostrich burger kabobs. Lots of potatoes and carrots, though.
