China - There is a gluten free restaurant in Flagstaff, AZ called Picazzos. It is wonderful. My heart goes out to your DD. And - I am aware of eating disorders. Man, it is a viscous circle. My friend obviously had a food addiction, which in itself is a struggle.
There are more and more places with gluten free menus. The real problem is cross contamination. If you go to a place and order a steak but the cook has flour on his hand when he handles the steak, or cooks something breaded in the fryer next to the french fries. Its a problem.
