Review of Richards' Southern Fried

We went today (4/3/19) with my newly-diagnosed 10 year old son. We looked it up online both here and the Richard's website to make sure it was GF. When we got to the counter to order the server told us the only things that were GF were the chicken and the collards. Not what he was hoping for. We still got the potato wedges and he ate them. My thinking (which could be faulty) is that if the chicken breading is GF, why wouldn't the "breading" on the fries be GF? Anyone have any thoughts or info on this? It seems like they really need to clarify exactly what is and isn't GF. Since they have a big GF on the store front, many people are going to assume the whole place is GF. My son really liked the food and I hope it doesn't make him sick.
