Adem Colpan, 30, is second generation owner of the Pudding Shop on Divanyolu street where Billy Hayes made the drug deal that landed him in jail and gave birth to the 1978 movie “Midnight xpress.” This is all most Americans know of Turkey, and it’s all wrong, say Turks and those who have visited Istanbul. “Some old hippies complain aboutthe changes (in Istanbul) when they visit now,” says Colpan. “But I say you are not the same either, now you don’t have dirty clothes and long hair, you have jobs. Times change.”
