"The 24-hour dining options outside the perimeter are extremely limited, but Marietta Diner on Cobb Parkway near the Big Chicken has been the place for 24/7 OTP eating since 1995. The Greek diner includes an impressively large menu to satisfy any craving, and that includes around-the-clock breakfast dishes. Try the grilled cheese, gyros, patty melt, or any of the open-faced sandwiches. There’s also fried chicken and fried catfish." - Beth McKibben, Eater Staff
