I am a very sensitive Celiac and I had no problems at Louie's. Our waitress was a Celiac herself, so she assured me that it was safe for me to eat there. She said that when she put gluten free on our order she had to specify it was for an allergy and not a preference. I would recommend reminding your waiter/waitress to do that, if you have an allergy. Their menu is clearly marked and you need to ask if their fryer is separate or shared, apparently it isn't all the time. I had the spinach artichoke dip, butternut squash salad and chicken piccata with no issues. I would say this restaurant is very safe for Celiacs.
