Just found Zeta's tonight for the first time. If you enjoy Mediterranian food, this place is the best we have found in the valley in the 9 years we have lived here. The Kibbee Nayeh was very good but the Lamb Shish Kabob was tasty, moist and tender, and the best I have had since leaving Michigan (where great Middle Eastern food is in abundance). Additionally, both the Fattoush and Tabouli salads were excellent. Everything was excellent and very traditional.
Nicholas was our server and he went out of his way to make sure we had everything we needed and that everything was perfect for our experience. Prices are reasonable as well, especially consider the price on lamb nowadays.
If you are in the area this restaurant should be on your must-stop list. If you live a little further out, it's well worth the drive. We will be going back soon.
