I can’t speak for the rest of the restaurant chain but the Chuy’s in Sterling was great! Jeff the manager was very kind and sat down and told us what we could have on the menu. We called ahead and they prepared chips gluten free, drained the fryer and refilled with new oil. The key is call ahead and let them know you are coming and you have a gluten issue. I had tacos and my daughter had nachos. The boom boom sauce was a great alternative to the queso which they make with a rue.
