We get the gluten free Shrimp Pineapple rice off the specialty menu. It’s very good. Spice or no spice.
— Gluten-free items are marked on the main menu
We eat at Ubon Thai whenever we are in the area. It's excellent thai food and they are very aware of which items are gluten free even though the menu doesn't indicate. If your server isn't informed about GF, ask to speak with the owner or kitchen. I have never had a reaction although I don't know if they have a dedicated GF prep area.
