I was really surprised to learn that JP China, in Alton Bay, now has a great gluten-free menu. The owner has switched to a soy sauce even that is also gluten-free - nice bonus. Anyhow, I can't see a link for it on their website, but they have menus in the restaurant with g-free selections and of course they have take-out.
