I would not consider myself an expert on Middle Eastern food, but Taza is good food, no matter the cuisine.
The food is very fresh and generally prepared correctly. The servers are usually attentive, and the decor is nice. The only complaint I would have is it seems to be a bit pricey for what you're getting, but I'm sure part of that is the location (the rent at Eton must be sky high).
I have family members that are Middle Eastern and they love this place, so that's a good sign.
