"The ordinance, if passed, would require all businesses that serve alcohol in the city to do what Keefer's Restaurant has done: post signs at the entrance telling customers that guns are not allowed."

Section 90. Preemption.
The regulation, licensing, possession, registration, and
transportation of handguns and ammunition for handguns by
licensees are exclusive powers and functions of the State. Any ordinance or regulation, or portion thereof, enacted on or
before the effective date of this Act that purports to impose
regulations or restrictions on licensees or handguns and
ammunition for handguns in a manner inconsistent with this Act shall be invalid in its application to licensees under this Act on the effective date of this Act. This Section is a denial and limitation of home rule powers and functions under subsection (h) of Section 6 of Article VII of the Illinois Constitution.
