The Potpourri House in Tyler, Texas is a restaurant and event space with a gluten free menu.
Here's the link to their gluten free menu: http://www.potpourrihouse.com/restaurant/gluten-free-menu/
They are not a gluten free facility, so the risk of cross contamination is present, but they will take extra measures to provide a safe meal if this is communicated with your server. Their gluten free menu has five different entree options, several vegetable-based sides, and a dessert option (petit brulee). They also offer a gluten free kid's pizza with gluten free crust, red sauce, mozzarella cheese, and pepperoni. None of their gluten free menu entree options are vegetarian, so it might be best to consult with the manager or server ahead of time if you are vegetarian and need a gluten free meal.
