I believe they had one other location and has closed 3-5 years ago. I guess because it didn't do the business nearly as good as Tonka Bay. I believe there is only one Joey Nova's Pizza. I've heard that the owners own other restaurants with different names. I suggest calling the head manager at Tonka Bay and they will get you in touch with the right person if they don't already know the answer themselves.
I only know of the Tonka Bay location but Google can give you the full story
