There are already a lot of positive reviews for Zeitouni, and it's for good reason. I'll chime in with mine as well.
The bottom line to why this place is good, is the delicious quality at a fair price. Some places tend to cut back on quality once the business is rolling for a while, but I've been going to this place since they opened, and thankfully thus far, it doesn't seem like they've fallen into that all too common mistake. (Paying Cisco 25 cents less for your ingredients is NOT worth it and will turn away customers.. thanks to Zeitouni for being a place smart enough to realize this.)
Quality ingredients make a big difference to me when deciding whether or not I like a place.
I'm giving it 4.5 stars... just because food sometimes takes a while, and some of the staff could be more friendly.
