Celiac daughters did not negatively react after eating here. They had kids burgers with GF buns, mashed potatoes and huckleberry lemonade. No issues but the server was not necessarily the most knowledgeable (e.g., "Anything with GF symbol is gluten free" though one was nachos with deep fried tortillas in a shared fryer but she didn't actually tell us, we just knew that already). So, stick to the simple things and it seems you'll be safe here.
