Sad news to report out of Coney Island: Kenny Rogers Roasters Express inside Nathan's, perhaps the last place on the East Coast to get KRR chicken, is being disassembled. Nathan's Famous had retained the right to sell KRR as a part of its sale of the chain to its Philippine franchiser in 2008, but ultimately, with very little remaining brand recognition, it probably wasn't worth continuing the operation. Nathan's is already using the counter to sell its own specialties, from hot dogs to chicken and fish sandwiches.
Barring any other Nathan's still selling KRR (I know of none), it now seems the only place you can still savor its chicken in the United States is at the Ontario Mills mall in Ontario, California. Miami Subs, also previously owned by Nathan's Famous, has also removed any mention of KRR from its online menu.
