Two epic road trips and multiple visits to New York left me happily full with amazing gluten free food. And I have a tonne of guides for you as a result!
Gluten free USA life is pretty easy in the big cities and just takes some planning if you are heading to other areas.
One thing to watch out for as a coeliac is that many place advertise gluten free that isn’t suitable for coeliacs due to cross-contamination. LA was the worst offender. You will always find something to eat, just remember to ask questions about cooking processes to avoid getting sick.
