I went through this thread and I have to echo the recommendations SohelNR and Electrequiem made, particularly Marquez and Murakami.
For those who like crime/mafia fiction - The Day of the Owl (Il giorno della civetta) by Leonardo Sciascia
For those who like satires about War: Catch-22 by Joseph Heller, Slaughterhouse-Five by Kurt Vonnegut, The Good Soldier Svejk by Jaroslav Hasek
For those who like magical realism: Along with the above mentioned books by Marquez and Rushdie, The Master and Margarita by Mikhail Bulgakov
For those who like short stories, which, for lack of a better word, warp your mind: Labyrinths by Jorge Luis Borges (You'll see how Inception was inspired by a few of these stories)
For those who like cultural history/social anthropology: The first two parts of the Ibis Trilogy (Sea of Poppies and River of Smoke) by Amitav Ghosh; In Xanadu and City of Djinns by William Darlymple
