Carmelo's Ristorante Italiano is an Italian restaurant in Austin (and Houston), Texas. They have vegetarian, vegan, and gluten free options available -- let your server know. They make a note to extremely gluten sensitive guests that they use wheat products in the kitchen, but they do their very best to avoid cross contamination. That being said, wheat flour in the kitchen can become airborne and cause minimal contamination, but they do their best to produce gluten free food.
Their gluten free menu can be viewed here: http://www.carmelosrestaurant.com/glutenfree and it covers appetizers, salads, soups, entrees, and desserts.
