daddy-o-biscuits question

hey y'all, I am heading out to columbus, Ohio in a few weeks and was wondering if you have been to daddy o biscuits. I was reading online reviews and for the most part it looks amazing, but I did see a few reviews from a few years ago mentioning that a few people got glutened from there. I have OCD about gluten contamination and am now a bit afraid to eat there. thoughts?
