All the restaurants that are two TS for adults are also 2 TS for kids. I agree though, the difference in price between a regular and signature restaurant (1 vs 2 credits) is very small for kids. So you are using double credits even though the cost of the food isn't double. That is why when we went to AP, I paid OOP for my kids. They ended up sharing one kids meal and we just paid cash, rather than using up their credits on this.
