Ordered burger with gluten free bun. Told waitress was Celiac and one crumb makes me very sick. She said there would be no problem and they could accommodate. The burger came with a regular bun. I questioned it (unfortunately after i had taken a bite) she again said it was gluten free (despite the bun looking exactly like my husbands gluten bun). She returned it to the kitchen and brought me back the same bitten burger with a gluten free bun. Told her I cannot eat it now that it has been cross contaminated. The manager covered the bill and we promptly left.
