London, Bazlama and Shrimp casserole

I am just back from a weekend in Ankara where I had the Turkish bread Bazlama served with a creamy shrimp casserole.

I use a number of Turkish restaurants (mostly Testi) but have never come across this bread before and I have never ordered shrimps, being distracted by the grilled meats.

Does anyone know where these can be found in London?
