Cannot argue their D rating. I was expecting a C. haha
but about being sick, I do not think it will make anyone sick man. You seem to have experienced their food too, have you been sick yet? I know I have not in the odd 3-4 years I have had them.

But its just my experience, yours might be different. I like their service, mostly the old employees. They used to laugh a lot at my stupid jokes, made me feel better :)

About improvements, there sure is. Just dont be too hard on them!!
