Cava, a fast-casual Mediterranean chain, has acquired Zoe's Kitchen and is converting some of its locations.
In the OKC area, I've seen plans for the Classen Curve and Quail Springs area stores. Not sure about Edmond and Norman.
Cava is a little nicer and features a Chipotle-like food assembly line where you can choose your base, proteins, spreads and toppings.
The image below is for Classen Curve.
