I think QS is decently priced, especially when compared to other venues like pro sporting events, other theme parks, or concerts. Heck even compared to fast food its priced somewhat fairly.
Alcoholic beverages on the other hand are overpriced IMO and are what pushes a meal, QS and TS, from reasonably priced to overpriced. We are doing the QSDP this upcoming trip, in large part due to the prices of mixed drinks. You want to hit an avg of around $27 a QS meal, just previewing menus, the meals we want to get a drink with will make it pretty easy to hit that avg (my Satuli meal I'd like to get is about $37 after tax for example). There is something psychological to me where it doesn't feel right to $15 to eat but then it would cost $17 more to add a mixed drink to the food.
