The Mangal 1 Ocakbasi on Arcola Street, Dalston, just up the road from Junction, is highly recommended by both me and Rick Stein. Lots of meat, done over open charcoal, lots of salad, BYO. Excellent (though I agree with some who lament the price increases since they expanded the place a while back).
As a former Haringey resident, I do miss Turkish food.
