State regulators have ordered two Lafayette bars with repeated offenses for selling alcohol to underage patrons to change their operations to keep minors from imbibing.

Nitetown and Arcadian Bar & Grill, two Jefferson Street establishments in downtown Lafayette, were called to state Office of Alcohol and Tobacco Control hearings on the infractions in January and December, respectively, ATC Commissioner Troy Hebert said Wednesday in a news release.

Nitetown was fined $5,000 following its Jan. 14 hearing for third-offense alcohol sales to patrons under the age of 21 and allowing minors into the club, Hebert said.

The business is now required to implement stringent measures on its employees to prevent future underage sales, including a zero-tolerance policy that will cost an employee his job should he sell to anyone younger than 21, Hebert said.

Also in the ATC agreement, Nitetown employees will be required to maintain a bar card, check ID if the customer “appears to be under 25 years old,” and report patrons without a valid ID card to management — who will in turn notify the Lafayette Police Department.

In addition, employees will be prohibited from selling alcohol to anyone with a vertical state driver’s license, which is an indication the person may be underage.

Entrance into the club will be further restricted, with employees checking each ID card with an electronic scanner, giving patrons over age 21 a coded arm band and marking every customer with a glow stamp.

The agreement also requires management to hold weekly employee meetings to re-enforce the new policies, Hebert said.

Arcadian, which was charged last year with a fourth-offense sale of alcohol to persons under the age of 21, agreed following its Dec. 11 hearing to surrender its alcohol permit and pay a $2,500 fine, Hebert said.

Arcadian’s owner Robert Zorn is banned from working as an employee, manager or owner of any business operating with an alcohol permit at the location, Hebert said.

“ATC appreciates the Lafayette Police Department for their efforts to prevent sales of alcohol to underage individuals. We will continue to work with the local authorities to make certain that these businesses abide by their agreements and that the public is protected,” Hebert said.

Two underage Nitetown patrons were most recently cited for alcohol possession Jan. 24 during a Lafayette Police Department compliance check.
