A $50,000 reward has been offered by the heartbroken family of Louis Barbati, co-owner of Brooklyn’s L&B Spumoni Gardens, in hopes of flushing out the thug who fatally shot Barbati outside of his Dyker Heights home Thursday.

“The family would like to see whoever is responsible for this arrested as soon as possible,” a spokesperson told The Post. A wake for Barbati will be Sunday and Monday at the Scarpaci Funeral Home in Dyker Heights.

Anyone with information should call Crime Stoppers at 877-577-TIPS.
