Are there resturants in the theater?

No

There is a Zaxby's located to the left as you approach the theater building and all other restaurants are located a good few blocks away including TGI Friday's, Chilli's, LongHorn, Moe's, and Red Lobster all located further down Camp Creek Pkwy(left at stop light)

Not in theater but in the surrounding area some you could walk to, others drive around the corner too within the plaza.

Just average theatre concession food
