For QS credits, the best QS restaurant is Wolfgang Express Marketplace in DTD. There is salmon, rotisserie chicken, pizza's (pepperoni, meatball, spicy chicken...), chicken strips, meatloaf wrapped in bacon, salads, sandwiches, pastas ... and for dessert, cream brule, cheesecake, frozen yogurt with fruit. It has refillable drinks and it is almost a TS restaurant (you have servers refilling your drink and bringing you your food after you have ordered it).
Some people will rave about Earl of Sandwich, but we don't love it - it's fine, but for
DDP value, Wolfgang Puck Express is much better value. If I was paying OOP, I'd probably be more likely to eat at Earl of Sandwich since it is cheap.
My teens like T-Rex for TS meals, but I have heard a lot of good things about Raglan Road.
