Restaurant Maroni was a restaurant of Italian origin run by the Maroni Family.
Before Arkham City Incident[]
At some point the Maroni family gathered at their restaurant to talk about how to finally win the war between themselves and the Falcones. As they talked, the building was surrounded by Carmine Falcone's men, who opened fire on the building. Most of the Maronis inside were killed, and their leadership eliminated. All of the remaining Maronis were incarcerated in Arkham City.
