I had an interesting experience here last Friday. I have celiac disease, and when I told the waitress that, she took it seriously. (I wish more places would, because we get sick when they don't.) After I ordered my dinner, three other employees came over to the table just to discuss the food that was safe to eat and make sure I'd ordered the right thing.
Something happened between my order and it being brought out, because the order was wrong and definitely not safe for me to eat. I noticed it and reported it right away. They brought out the right food quickly and apologized and insisted the dinner was on them. I was impressed with the attention and effort. Mistakes happen, and they were really gracious about it. I will return. :)
