Mayor Christi Fraga’s latest move could dim the neon lights of Doral’s nightlife. In sweeping proposals sparked by the deadly April 6 shooting at Martini Bar, Fraga seeks to shut down alcohol sales at 1:30 a.m., and roll down the shutters of bars and nightclubs by 2 a.m., a curfew that some say could clobber the city’s after-dark economy. The proposals, coming to a vote at the Doral City Council meeting this Wednesday, are named after George Alejandro Castellano, a security guard who died in the incident that left two dead and several injured, WSVN reported.
