Vacationing and Eating Out

My family is going to California in two weeks and I'm starting to get nervous about food because we are going with lots of family that can eat anything. I know Disneyland has a food allergy guide (but where do I get it?), and I know I am pretty safe with Mexican food and Chinese food. I've also had success with Olive Garden's new gluten free pasta. But, what else is there? Any ideas? Or any knowledge about places in the Anaheim, CA area where we can eat sans problems (dairy and gluten allergies)?
