Aaah English beer, almost a good enough reason to return to England. I seem to remember (i think is was Starman) saying it was available last year up in Istanbul, so I thought the reason we didn't have any was just down to the local import company rather than countrywide import problems.
The only alternatives to crappy Efes I know of are other crappy Lagers like Fosters, Becks, Miller, Skol etc.
Efes Dark is a little more tolerable but its still not a proper beer!
