Choose your answer: is the following review positive or negative?

This place is failing in every way: their service is dismal, their food is greasy/tasteless/disgusting, and the kitchen/dining room are absolutely filthy. I have no idea how or why they continue to remain in business, but I would suggest that if you ever must make the mistake of consuming this disgusting excuse for food, then for goodness sake dine in.
