Happy hour drink specials have been banned in Illinois since the late 1980s, but they could come back under a measure awaiting the governor's signature.
The proposal would restrict specials to four hours a day and no happy hour deals after 10 p.m.
Its sponsor, Democratic Representative Sara Feigenholtz from Chicago, says it modernizes the law.
"All local governments are allowed to make those changes if they want them to be lower,” Feigenholtz said. “They can't go beyond what we've done, but they can certainly go beneath us. So I believe the bill is a reflection of the current marketplace."
Some opponents say happy hour specials lead to excessive drinking and drunk driving.
The measure passed the Illinois House and Senate and now needs the approval of Governor Bruce Rauner.
