Lately, my friends and I have been frequenting Nazar, a Turkish restaurant in Sunnyside that serves up delicious eggplant appetizers and chicken and lamb kebobs. We always conclude our meals with Turkish coffee, which is served black, and slightly sweet and muddy, in an espresso cup. Normally I don't drink coffee, but I love this stuff. I've been to several coffee specialty stores asking about "Turkish coffee" but I get the feeling I'm barking up the wrong tree. Is there such a thing as Turkish coffee? Or is it Nazar's little secret?
