Diet Cherry Coke fans rejoice…the flavor is coming back as a permanent offering. The company has yet to officially announce the big update, but there was a buzz about the news at a trade show in Chicago last week. Food blogger Snackolator posted “I spoke to Coca-Cola at NACS and they confirmed this is a ‘sustain’ item which means it is intended to stick around so hopefully it sells well and stays FOREVER this time.” Now it’s wait and see.
