JoAnn died on Friday 13th in 2009, along with my investment
The concept would have performed better during the 1970's -- rather than the 1980's and 1990's, IMHO.
She and Leonard Doctors, the franchisors, proved that location is everything. Almost every one of the stores failed in the first two years. The seedy location on Atlantic Boulevard in Jacksonville, where the restaurant began, was a strip club -- before after she went out of business.
As for the recipes, come on. Really? If you owned a franchise, like I did, you know that you had to buy the seasoning packs from Leonard and that you never were told the recipes.
Oh, and the recipe for the hottest chili (always the last item on the menu) was actually called "Madame Hot Pants" and I DO know the recipe for that -- it was whatever was left over from the five or six flavors from the previous day, doused with cayenne pepper; so, it was really never the same each time you had it.
