Update as of 8/13/17: It has been a year and I couldn't wait for Bob's again. This time I definitely had contaminated food and felt awful. It had been such a good experience a year ago that I went back. I won't do that again. In Bob's defense, they were very open about the risk. I just really wish there were GF clams somewhere!
I ate the GF clam strips, tartar sauce, and onion rings. The cashier told me they now fry all GF requests in the french fry oil, not with other gluten containing items. That being said, it's still not a GF kitchen. My order was on the same tray as the three other items I ordered but it was marked with a frilly toothpick. In the future I will ask for a separate tray. I did not react to the food, which is great because my family has been eating here for decades and I have missed their food so much!
