     When first entered, Vanak Restaurant does not look like much of a restaurant, but once the pleasant

smells of kabob(烤肉串)hit the senses, you are incapable of calling it anything less.

     Owned by a local couple, this Persian restaurant has an inviting, homelike atmosphere that many

restaurants lack.

     The space is small with only a few dining tables and nearly no decoration, but the environment is truly

charming.

    Lying in a hardly noticeable street corner, the restaurant still attracts all customers, especially those

experienced in the delights of Middle Eastern cooking.

    A common sight is that of old Persian men sitting in the corner talking loudly about world topics,

watching news events on TV, drinking a black tea known as Persian chai, and reading local Persian

newspapers all the while trying to finish off their plates piled with food.

     The variety of food at the restaurant is limited, but the amount of each dish is fairly large.Most of the

meals can serve two people and are under $10, so not only is it affordable but practical as well.

    The food especially appeals to healthconscious eaters because each dish is very healthy, made with

limited fat and oil and served straight off the grill (烤肉架).

     The main dish that the restaurant is popular for is its kabobs, which are different styles of grilled meat.

    One delicious and extremely healthy dish is the Joojeh Kabob, which is made of grilled chicken pieces

served with either rice or bread.Another great kabob is the Chelo Kabob, a kabob consisting of grilled

beef.
