Hey-So my dad love love loves middle eastern food(I have just relocated to NYC, and they visited brooklyn w/ me, and were in heaven at the amazing, cheap middle eastern food there).
He didn't like "always fine dining," the only option that i know of here. So- help me find him a father's day treat nearby. He's particularly fond of Armenian and Lebanese food. Although I'm not sure if it is technically middle eastern, Morrocan food is a source of joy, as well.
