Mr. Delicious was the spokesman for “Rak” Restaurants, a food chain that resembled Arby’s and Wendy’s.   Contrary to popular belief, the Mr. Delicious ads had nothing to do with the demise of “Rak”.   “Rak” was acquired by “Hardee’s”, which planned to convert them, but through various attempted acquisitions  (even Wendy’s), “Rax” filed for bankruptcy.  There are still a half-a-dozen “Rax” restaurants left, mostly in Ohio.
