I had salmon, fries, and broasted potatoes plus some of the prepackaged snacks, all of which tasted great and I did not get sick. Expensive, of course, but seems like one of the safest options in the airport. Each item has a placard with GF/dairy-free/vegan marked for each item. If I I'm stuck in DFW and have time and money to burn, I would eat here.
