I've had breakfast and lunch several times here without any problems. They do not have a GF menu, but they do have very good GF bread which they can use to make most of their sandwiches and also for toast with your breakfast. For breakfast, I usually just order the toast with bacon, eggs, and hash browns. Never had a problem. I didn't ask about their prep area, but I suspect it is common, so the risk of cross contamination is high if you are super sensitive (fortunately, I am not!).
