Lots of gluten friendly options at Bangkok Buri in the food court at Union Station. The online menu is clearly labelled and the staff members are aware of proper precautions to take. All sauces and curries are vegan and gluten free. I ordered the chicken pad Thai - there are other rice, noodle and salad options that are gluten free as well.
