Bar Rescue is a show that is on Spike TV. Jon Taffer is called to help out failing bars in the hopes that the bar can become successful again. After watching the first three seasons of the show, it seems to me that he is able to improve the finances of the majority of the bars he fixes.
I haven’t quite figured out exactly what all the “bar science” involves, but can confidently say that the show is entertaining. While I have no interest in opening a bar myself, I still was able to learn a lot about what not to do. There were certain big mistakes that several bar owners made that stand out.
