mm yeah there is a Wendy's and McDonalds on Miami Blvd, which is one exit off of i-40 or you can take the back way, Also on Miami there is a Rudino's (pizza joint). Soutpoint Mall is 15-20 min drive west on I-40. Going East on I-40, there are several resturants at Airport Blvd exits and cary exits.
You can ask the front desk of any places that is close and also the pizza's places like Dominos deliver, so that is an option.
That is the bad thing about this con is that there are no resturants close, at least walking distance.
I've never eating at the con resturant but I hear its not that good and very expensive.
I hope this helps, I drive by there everyday to go to durham to work.
Be careful of all the road construction!! Esp. at the con exit
