What is the sentiment of the following review?
Myself and two co-workers had lunch here today. It was the worst Mexican food that I've had in a loooong time. The food was over-priced, burned and poor quality meat. My coworkers and I gave the server our feedback in a constructive manner. He apologized, but didn't tell the manager or do anything further. We won't be back. There are soooo many other great Mexican restaurants in town, don't waste your money on this one.
