Are you asking about prices? Amount of food? Quality of food?
There is really no easy way to answer your question. Some of the in-park QS locations will be more expensive and some will be less; it all depends on what you're planning on eating. In terms of quality, the same applies. Some of the in-park QS are much better than AoA and others are not. If you're already in a park, I would probably opt to eat there instead of taking the time to travel to AoA and then back to the park after lunch.
