Thats been my experience. Complaints generally center around not receiving 3 Michelin star service while paying for $18 entrees.
My favorite are the people who list their dining resumes and establish their credentials before stumbling their way through a review. "I've dined at Daniel, Per Se, and Le Bernadin, so take my word for it when I say that Chili's has the WORST general tsao's chicken that I have EVER had!!"
