re: Worst restaurant experience you've ever had?

Worst ever for me was at Boutin's on Bluebonnet (since closed, go figure). Was there with my wife, child, and in-laws. There were about ten tables seated there. In my approximately hour and a half there, I never saw any other table receive food. Waitress could not answer a single question we had about any item on the menu and she never offered to find out the answers. Never got our food. It was the only time we ever walked out of a place without waiting for entrees.
