    I don't have a smashburger around me. I didn't know what to expect but I was pleasantly surprised. I ordered their gluten free bun (which was one of the bests I've ever had), the employee ask if it was an allergy so they could tell the cook to prepare it on a separate grill. Employees were really nice and knowledgeable about the situation.

    I'm surprised so many have voted this place celiac friendly. I was told the burgers are cooked on the same grill as their grilled cheese (and not cleaned in between). We ended up not eating there and left

    Staff very knowledgeable about cross contamination. Grilled my gluten free bun instead of toasting. Fries are fried in dedicated fryer. Delicious

    Excellent. Knowledgable staff and dedicated fryer. Manager states she is very cautious now of making shakes because if an issue they had with cross contamination. Great burgers.

    Great food, got a burger with a gluten free bun and fries. Staff very knowledgable and toasted my bun on the grill instead of the toaster. All seasonings on the burgers are now GF.

    Recently partnered with Udis for GF buns. Changed spice mix on burgers and chicken sandwiches to be GF. Fries are prepared in a specific fryer to avoid cross contamination. Cashier was knowledgable on their processes and ingredients. Ask them to not toast the bun if you are concerned about cross contamination since the toaster is shared with regular buns.
