An item on the menu was denoted as gluten free and it was not, resulting in severe illness due to celiac disease. When the restaurant was called and notified, they said the GF next to the item was actually only referring to a footnote indicating that options were available. I told the manager that the GF next to an item usually means that it is gluten free at every restaurant in which I have ever dined. I also stated that this confusion resulted in illness and that the menu should be clarified immediately. I will not be dining here again due to their laissez faire attitude toward this serious issue.
