i have only see this dish in calis not any other parts of turkey.
Like many of these "ottoman" named dishes, each chef/cook will make it the way they think it should be made. As regards Topkapi Chicken, some will stuff the chicken breast, other wont - the rest of the ingredients will change depending on a) where you're eating it, b) how much you're paying for it and c) what ingredients are readily available at the time.
You could look at books by authors such as Claudia Roden, Greg Malouf or Rebecca Seal, or try for an English version of Sharon Croxford & Özge Samancis Flavours of Istanbul, where you may find an approximation of what you're after. These are all in English - if your Turkish is up to it (mine certainly isn't now!) I can also recommend some Turkish authors who specialise in Ottoman cuisine.
