I've eaten lunch here a couple of times and I have been very pleased with my meals. The service is good, though it seems that the kitchen staff is a little slow. Don't stop in here thinking you can cram a meal into your 30 minute lunch break.
I have tried a number of items here and found them all to be delicious. The portions are very generous and I've never been able to finish an appetizer and meal. Generally I split the hommus and lebne with a coworker, we each get a meal, and we take most of everything home as delicious leftovers.
Check out the bakery, the baklava is decent and it's cheap- plus they have varieties that I have never seen, like almond/hazelnut. And you can't go wrong with fresh, warm pita!
Recommended: Hommus, Hommus Deluxe with Lamb, Lebne (best I've ever had), Shish Kabob pita combo (comes with a drink and fries for $7.99), and the Gyro Platter.
