The Billy Goat Tavern is a famous tavern in Chicago originally because it was a rowdy and popular sports bar. It used to be located across from the United Center which is now the home of the Chicago Bulls and Blackhawks. The owner came into the adoption of a lost goat and so it gained its name.
Most people are mistaken about the back story to this pubs fame. I read a visitors post on here to the Billy Goat that is located on Michigan Ave, which is a tourist trap. The true fame of Billy Goat was born out of a television show skit. The show was Saturday Night Live and they were mocking the stereotype of Chicagoans. In the skit they would shout out "cheeseborger cheeseborger!!" And become quite obnoxious. The tavern never did this. Except to bring in business when slower after the skit aired. But the recognition of Billy Goat on national television has attracted thousands and thousands of tourists a year.
