Staff was pretty rude and wouldn’t answer my questions about whether something was actually gluten free. I finally asked for a manager to get the info I needed, though it contradicted what the server had said. I didn’t get sick but definitely consider this a high-risk place for celiacs.
I ate here last night and asked about the chips. The server explained that, yes, the chips are fried every morning but, no, not necessarily in clean oil. They only change the oil a couple times a week, so if you're thinking of ordering the chips and salsa be sure to ask if the oil was changed that morning.
Most of their menu items are gluten free and the staff was very helpful with pointing out what items are not gluten free (typically just items with flour tortillas or nacho cheese), so there are lots of options if you are GF and there are some vegan options as well.
