Hat Creek Burger on 79 in Round Rock is the best for a gluten free burger. When they opened, the did not have gluten free buns, so I brought my own and ordered the "burger bowl" which is (for me) a turkey burger with lettuce, tomatoes, pickles, and cheese. After a few times marching in there with my own bun, they have all gluten free buns now! They have a separate area to prepare gluten free food. I believe all the condiments (sauces) are now gluten free, but be sure to ask, because one sauce used to have gluten in it. French fries are cooked in the dedicated gluten free fryer. Great service, fast at the drive through, and if you have little kids, a wonderful playground for them outside. LOVE LOVE LOVE HAT CREEK! Safe for celiacs? Yes I think so. I've eaten there dozens of times and never gotten "glutened" unlike some places who say they are gluten free.
As far as I know, all the food is gluten free but ASK, always.
