We live in AZ, but travel to southern Cal. often. We are a pn/tn ultra careful/free family. We like La Salsa, Chipotle, BJ's Brewery (favorite is on the ocean in Laguna Beach), and Maggiano's which are all chains. For a treat, even if not going to Disney, consider when in Anaheim eating in the Grand Californian hotel at Storyteller's. Make a reservation. They will accommodate all of your allergies and are awesome. All Disney property restaurants will do this for you. My friend's who live in Irvine eat at El Torito, too. If you have a daughter, the American Girl store restaurant in LA will also accommodate your allergy needs. Hope this is a start. Oh, also, Nordstrom's accommodates allergies, too and they are all over LA area.
