Al-Tazaj
When it comes to speedy service, McDonald's could learn a thing or two from the Saudis who own Al-Tazaj. They claim to get their produce from farm to grill in fewer than four hours, which is why (despite the fast-food joint look) this place turns out juicy grilled chicken—and little else. The birds are small, so you might want two; and while you're at it, ask for an extra container of the garlicky tahini to use as a dip.
