My Israeli friend went to Greece and ordered Turkish coffee. I'm not from that side of the world but I know BETTER than to ask that. He got the 'look' and they told him he should just call it 'coffee'.
It's a strong cup of coffee that can be sweetened by 'cooking' it w/ sugar. It ends up w/ a muddy residue (which you don't drink). It's espresso on acid. I LOVE strong coffee and this is what I drink when I can afford staying awake.
I say strong because I know lots of people that go to Peet's for strong coffee because they think Starbuck's is too 'light'. Peet's barely has even any taste for me. I definitely prefer my own coffee and miss it when I'm on vacation.
