I've never gotten sick here, but you need to be careful. People get different answers about the fries, but once I had it explained in detail. There are separate fryers, but they sit next to each other and splatter into the other. That's quite disappointing, but the fact is that my Mom (who is not a very sensitive Celiac) eats the fries without problem. I would never try it because I am very sensitive. I only eat the burgers on the GF bun (not toasted). 1 burger isn't enough food. 2 burgers is too much burger without a side. Nonetheless, it's good in a pinch. I've eaten there probably a dozen times safely.
