Sal Britoni is an Italian-American actor from Liberty City. He has won numerous Academy Awards. He is known for his roles in the films "Little Italy", and "Cabbie", where he portrayed as pyschopathic Las Venturas taxi driver. One of his most famous movies was 1994's "Mafia". Posters advertising "Mafia" can be seen around Star Junction and Westdyke. Britoni's name can be seen at the bottom of the poster.
Britoni is presumably a parody of actor Robert De Niro. "Little Italy" is a spoof of "Mean Streets", as is "Cabbie" to "Taxi Driver" and "Mafia" to "Goodfellas" and "The Godfather"
