This a classic diner with likely the pitfalls that come along with it for grill cooking. I am not reactive so I can’t say for sure if there was CC but I wouldn’t risk bringing my highly reactive celiac sister. Gluten free items are indicated on the menu and the website allows you to filter for GF for online orders, which limits your selection to omelets and the house salad. They have GF bread to modify a sandwich. We weren’t blown over by this place but I know it has a loyal following.
