Love love love Conflict Kitchen. Low-key, affordable, DELICIOUS, thoughtful. Sitting right in Schenley Plaza is Conflict Kitchen--now in stand form. Right now they're featuring Iranian food, and everything I ate and tasted was knock-your-socks-off yummy. Nice flavor combos, and nothing too overdone. Simple, great food.
You can get food and eat it at a table nearby, or you can get food and stroll.
