1) Actually, anywhere except Signature restaurants where prices are high.
2) Paying higher prices, others usually want less kid problems.
3) Other than that, all WDW eateries are good for kids.
Crystal Palace- I find this good lunch selection and good character interaction
Tusker House Donald's Safari Breakfast- I feel this is the best character buffet and I do like the character/kids parade...my son had a ball playing the musical rattles.
Cape May Cafe- Characters came to our table more than 2x
1900 Park Fare - Grand Floridian
"Playhouse Disney's Play 'N Dine at Hollywood & Vine" - one of my sons favorite but the lunch food is ok but we keep going b/c my son loves to dance with the characters...one of the best interaction with characters. Characters came to our table 3x. I do like the breakfast buffet
