Illinois turned back into a pro-happy hour state this week, after legislators overturned a 25-year ban on bars and restaurants discounting alcoholic beverages for any period during a day. It joined the likes of Kansas, which made happy hour specials and other drink promotions legal once again in 2012, after 20 years of prohibitions banning such practices. Yet several states still do not allow “happy hour,” meaning a period of time during a day when a bar or restaurant reduces the regular price of drinks.
