If you’re looking for an unusual place to grab a drink or two with friends, you might want to check out this special pop-up bar that’s coming to Illinois. Have you ever heard of a speakeasy? It’s a type of bar that was started in the United States during prohibition. It was illegal to sell alcohol during that era so underground clubs opened where they sold booze even though it was against the law. Customers had to know the secret location and password to get in to avoid the police.
