Please answer the following question: Generate a question that has the following answer: pizzeria for the following movie plot: Mookie (Spike Lee) is a 25-year-old black man living in Bedford-Stuyvesant, Brooklyn with his sister, Jade (Joie Lee). He and his girlfriend Tina (Rosie Perez) have a son. He's a pizza delivery man at the local pizzeria, but lacks ambition. Sal (Danny Aiello), the pizzeria's Italian-American owner, has been in the neighborhood for twenty-five years. His older son Pino (John Turturro) intensely dislikes blacks, and does not get along with Mookie. Pino is at odds with his younger brother Vito (Richard Edson), who is friendly with Mookie. The neighborhood is full of distinct personalities, including Da Mayor (Ossie Davis), a friendly local drunk; Mother Sister (Ruby Dee), who watches the neighborhood from her brownstone; Radio Raheem (Bill Nunn), who blasts Public Enemy on his boombox wherever he goes; and Smiley (Roger Guenveur Smith), a mentally disabled man, who meanders around the neighborhood trying to sell hand-colored pictures of Malcolm X and Martin Luther King, Jr. While at Sal's, Mookie's trouble-making b-boyish friend, Buggin' Out (Giancarlo Esposito), questions Sal about his "Wall of Fame", a wall decorated with photos of famous Italian-Americans. Buggin' Out demands that Sal put up pictures of black celebrities since Sal's pizzeria is in a black neighborhood. Sal replies that he doesn't need to feature anyone but Italians as it is his restaurant. Buggin' Out attempts to start a protest over the Wall of Fame. Only Radio Raheem and Smiley support him. During the day, the heat and tensions begin to rise. The local teenagers open a fire hydrant and douse the street, before police officers intervene. Mookie and Pino begin arguing over race, which leads to a series of scenes in which the characters spew racial insults into the camera. Pino and Sal talk about the neighborhood, with Pino expressing his hatred, and Sal insisting that he is not leaving. Sal almost fires Mookie, but Jade intervenes, before Mookie confronts her for being too close to Sal. That night, Buggin' Out, Radio Raheem, and Smiley march...
