Warner Chinese has an extensive selection of gluten free options all marked on their menu. Eaten there countless times and never have had an issue. There are coeliac staff members who work there so they are always very good with gf orders.
Although menu prices are a little higher than “your average Chinese restaurant”, it is definitely worth it for being GF and the portion sizes are very large
