I found the diner on findmeglutenfree app and then pulled up their menu online. I found only 2 gluten free options. I then called the diner and asked about their gluten free items. The manager told me they have gluten free vegetable soup and gluten free bread and buns so I could have my hamburger without a problem. I then asked if they grilled their gluten free bun on the same grill as their gluten buns and he said yes. I commented they weren't gluten free and he agreed. He said they offer gluten free bread but do not cook it separately to prevent cross contamination. He commented they are not a gluten free facility.
No
