They won't heat things up, but they are very accomodating. SIL has a 14 month old and we frequent the restaurants with them all the time. While the baby eats most everything now, we've had places bring her plain pasta, yogurt, hot water for cereal, plain chicken breast and turkey, cooked veggies, etc., with little or no charge. SIL always travels with food for the baby (she's always made her own) "just in case" but has never had a problem at Disney.
