We very well could've gone on an off night. My steak was good. My wife's was very meh. Average. I told her she should ask them to take it back and fix it, but she's just not confrontational in that way, so I asked for her. They did it, but the looks and attitude were enough to make me not want to go there again. She ordered hers medium and it was scorched earth well done.
I wouldn't say what I had at Libertango was better than what I've had at Ruths Chris. I've learned it also has a lot to do with location. Some are run better than others.
