I wouldn't say the staff was knowledgeable, but this is a tiny cafe inside the Carlsbad caverns Gift Shop at the National Park. They had a few salad options, all were gluten free, pre-made without croutons. You can pick your own salad dressing from the packets in the fridge under the salad. They might have options in the hot food bar, but the salads were the safest option! I didn't get sick afterwards, and the salad was pretty good!
