There are several options at DTD. We were there last month and tried Wolfgang Puck Express for the first time and it was great. You order your food, they give you a number, you find a seat and then they bring you the food on real plates with real silverware and there are waiters and waitresses to bring you refills on your drinks. We also ate at the new T-Rex restaurant, service was good as well as the food, considering it had only been open about 2 weeks at that point. We went early on a Thursday night, around 6pm and only had a 25 minute wait but it can be very crowded and a long wait. And it's LOUD in there with the dinosaurs. Earl of Sandwich is great counter service, reasonable prices, great food. They have sandwiches, soups, salads, etc. Lots of seating inside and out. There's also Cap'n Jacks, McDonald's, Raglan Road has a counter service side as well. You might need a reservation for Fulton's Crab house, Raglan Road sit down, etc.
Good luck!
