They have KFCs by the dozens, but I don't recall seeing sister Yum brand Arby's anywhere.
Arby's is not part of Yum brands. It is owned by Inspire Brands.
Well, there you go.
I coulda sworn I'd seen locations coupling the two. (not here, of course) Probably just misrememberating.
Arbys has by far the most creative menu + food among mainstream fast food chains imo. Roast beef, Brisket the best.
