If you do not have all season dining, I strongly recommend getting all day dining. The food at Cedar Point has gotten pretty good in the last few years, but if I paid $26 for a meal and drink, I would be very upset by the portion sizes.
Back Beat Que can be very good, but inconsistent. My two recommendations are Grand Pavillion and Farmhouse Grill (Do this one later in the day as there is a limited amount of shaded seating).
It is amazing how much better the food has gotten over the last few years at Cedar Point.
