The Oregon Liquor Control Commission voted to begin the process of banning Oregon restaurants from advertising their happy hour specials and deals.The staff recommended a ban on prices to prevent price wars that could lead to over-consumption, said Linda Ignowski, the agency’s regulatory director. The Commission and alcohol prevention groups have a history of disliking happy hours, due to their tendency to attend alcoholics. This issue has sparked the arrangement of public meetings in the Portland area. A formal public hearing will take place in February, and a final proposal for changing the happy hour rule will probably go back before the commission in March or April, Ignowski said.
