The actual name was given by the musicologist Giulio Confalonieri. The legend says that the scholar, fond not only of Cherubini and scopone, but also of palms and tropical landscapes, named it so in opposition to the grey Milanese days. Confalonieri would have taken inspiration from a 1939 English movie, “Jamaica Inn”, starred by sir Charles Laughton and Maureen o’Hara and directed by Alfred Hitchcock. Thanks to the success of the movie , released here in Italy at the end of the war, the Jamaica sign became one of the most famous in Italy. A unique atmosphere grew up in the place, contributing to make Milan a capital of culture. That period would never come back and it is not easy to make clear the reason of this. The Proximity to the Accademia had always attracted students and models, but the artists arrived in a great number starting from 1948, when the manager Elio Mainini organized an art exhibition named “Premio Post-Guernica”, joined by some artists of group “Consorzio di cervelli”: Gianni Dova, Roberto Crippa and Cesare Peverelli, and others such as Bruno Cassinari, Sambonè, Ernesto Treccani and Ennio Borlotti. 
Then they were starving. Now many of them are known and famous all over the world. In Those years a method of artistic exchange was born that didn’t have (and won’t have) equivalents in world: paintings for food, hired cameras, work of art lost playing cards, wine sold on credit (such bills most of the time were never paid) by “Mamma Lina”. This old fashioned lady was a strange patron, who gave credit without security and refused to accept paintings as payment in order not to exploit the artists in their need. But the true mind was her son Elio Mainini, who chose the wines and, reading the few American newspapers arriving in Italy, always proposed new cocktails, updating them according to the demands and whims of his customers. He was the one who accepting his friends Arrigo Cipriani and Gualtiero Marchesi’s suggestions, proposed to the Milanese carpaccios and the most sophisticated canapé accompanied by the most refined wines. From his untameable curiosity and from his enthusiasm the by now historical sandwiches, the Cesar’s Salads imported from America and the first Italian school for sommelier, established together with Gualtiero Marchesi, were born.
At the end of the70’s the acknowledgement of the city arrives thanks to an official merit of the mayor to Mamma Lina: for her Jamaica and above all for her success in creating that bohemièn atmosphere which brought Milan to be a capital of modern art recognized and admired all over the world. In those years even the poet Allen Ginsberg, mouthpiece of the beat generation, used to spend there whole afternoons.
