I called the restaurant, and the woman who answered the phone checked with the chef to see what items were gluten free. She found out that only the flour tortillas and the grilled chicken contained gluten. Willing to take a chance, we talked to the waiter when we were seated, and he confirmed what we learned and added that the corn tortilla chips were fried in corn oil in a separate fryer. After all was said and done, I enjoyed a hearty meal without any gluten reactions.
