Roberto is a restaurant owner who has ties with Carmine Falcone.
Mario and Lee visited Roberto's restaurant for their rehearsal dinner, based on Carmine's recommendation. When they are finished with their meal, Roberto has his valet pull Carmine's car around to the front of the restaurant. When the valet starts up the car, it explodes. It was later revealed that the Court of Owls orchestrated the attempt on Mario's life this way.
