Luigi Risotto

Luigi Risotto is the proprietor of the Luigi's.

History
Luigi often treats his customers rudely, insulting and belittling them; at times under his breath, at other times in a conversational tone, and sometimes shouting the slurs to the (unseen) chef Salvatore. Luigi seems to have some connections to the mafia. Local gangster Fat Tony is a frequent customer at his restaurant, despite the fact that he was one of the targets of Fat Tony's plan to get rid of all other food retailers except Marge's. He says the phrase, "I guarantee" a lot.

Luigi may have been an illegal immigrant because he disappeared during an immigration officer's introduction at Luigi's restaurant and took the citizenship exam with Apu.

When Homer was a food critic, he gave Luigi's eatery a poor review; in retaliation, Luigi hired a friend to place a horse's head in Homer's bed (a reference to ). Homer subsequently ate the head and gave it a bad review.

Fat Tony had Luigi on his list of people he should not shoot.

Luigi can't speak Italian but fractured English as it's what his parents spoke at home. When he ordered cheese for his lasagna he took help from Milhouse with the translation.

Because he is a member of the Hollywood Foreign Press he was selected to tell Bart that Angry Dad was nominated to a Golden Globe.

Trivia

 * In The Simpsons: Tapped Out, it is implied that Luigi isn't actually Italian. Homer overhears him speaking in a British accent, implying he is actually from England. Also, one of his jobs is to practice his Italian accent. The canonicity of Tapped Out is unsure though.
 * The prototype figure of Luigi from the World of Springfield toyline had a gray mustache.

Behind the Laughter
Luigi is a parody of the "Italian pasta/pizza chef" stereotype, but seems to be aware of his status as a stock character. His surname is a reference to the Italian food risotto.
