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 decor) this joint turns out some of Cairo's tastiest 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 deliciously garlicky tahina to use as a dip. Only the slightly soggy corn on the cob disappoints.
