As Sharon explained...
All character meals are very good values for kids. Dinner character meals are good ddp value for adults.
Character breakfasts, and some lunches --- are losers for adults.
Sticking to regular TS -- they are marginal values for adults and kids. For adults, regular TS can easily be a loser, but really depends on which restaurant and what you order. You must want dessert, and must order a $27+ entree (steak typically). Of course, there are whole restaurants without any entrees over $25.
