I'm not qualified to speak to the authenticity of the menu, so I'll stick to what I do know.
Khoury's is a good place for lunch or a light dinner, or for a party of friends who don't mind sharing plates. Their appetizers and tapas style dishes are their strong suit. I never did enjoy an entree, here (dry and bland seemed to be a theme).
The fresh bread is outstanding, and excellent for scooping up hummus, babaganoush, and the cucumber yogurt dish they offer.
For someone like me, who wants to order one of everything, the bill can get out of hand in a hurry. But if you're with friends, or at least one similarly minded companion, then the prices (again, for the apps and small plates) are perfectly reasonable.
Service was always friendly and prompt, though since the bread is fresh from the oven there can sometimes be a wait for more.
Seating is comfortable, inside or out. They have no problem moving tables around to accommodate parties.
NOTE: if you have dietary restrictions, you may want to think twice...the servers weren't able to answer our questions re: gluten and nut allergens. So, if you have a serious allergy, you'll probably want to try and contact the kitchen directly.
