Baiz is a great place for your Middle Eastern grocery shopping needs. They are stocked with items such as imported mango juice, fresh pitas, a variety of feta cheese, yogurts and kefir cheese, frozen parathas, etc. In other words, if you need some Middle Eastern grocery items, you will probably find them here.
The prices are mostly reasonable and the place isn't the cleanest. But, I still recommend Baiz as a top Middle Eastern grocery market in Phoenix.
