I have no idea where such a list might be as this is highly subjective. It depends on whether you have kids, on which meal of the day it is, on how you want to eat as a family......
However, the less expensive TS restaurants for general use are:
The Plaza (MK)
Liberty Tree Tavern (lunch MK)
50s Prime Time (HS)
Sci-Fi (HS)
Kona (breakfast Poly)....just about any TS a la carte breakfast will be best OOP as you lose your dessert option and even most breakfast buffets as they are all around $25. BUT you do want to use kids' credits at ALL buffets.
If you want to list the places you're thinking of, which meal, and make-up of your party, we could be of more assistance.
