I was able to eat the Cow Pig burger with no bun and duck fat fries without getting sick. Though they do have gluten free beer/cider, they did try to tell me the O'Mission brand was gluten free (which it is not) so this made me question their knowledge.
No GF menu or markings and our waiter seemed very unsure of ingredients. He specifically stated the homemade fries were only seasoned with plain salt. They arrived covered in a sometime of seasoning and the burger was overcooked and small. Service was slow but friendly.
