The help may not always be the friendliest, but why should they have to be? The food is so good they don't need to be nice. It's worth a trip to Ali Baba just if it's to find out what real hummus is supposed to look and taste like. Every other dish is authentic Lebanese with plenty of distinctive Middle Eastern spices. Servings are plentiful, but what may seem like tons of leftovers (that made your car stink like garlic while you went drinking in Lower Greenville) probably will be devoured before dawn.
