We had been to this restaurant before without problems. The food is a "b-" but it's close to the house. We visited last month for dinner and the bartender had a lunatic episode, came to the table cursing and yelling about nothing that made sense. He thought we were someone else, or he had some personal event or personal problem that caused him to become irrational and out of control. It was bizarre.
The manager couldn't control him and tried to pay for our meal. We paid anyway and left. Owner refused to explain what happened and his response was pretty textbook. The bartender should have been fired!
This was the worst behavior we've ever seen at a restaurant. The owner handled it terribly. With so many other great Mexican restaurants in the area - no need to ever go back to Taco Rosa again.
