How is a Chaldean restaurant different from the more familiar Lebanese? Many dishes are the same, but owners Saad and Zeana Attisha add, for example, pickled cabbage, purshee, that’s served to everyone as a starter, plus some tomato-based stews. And their daily specials are Iraqi favorites: burgul (bulgur wheat) on Tuesdays; biryani on Wednesdays (like Indian biryani but less spicy, with rice, chicken, beef and potatoes); pacha on weekends. New Sahara does better on the traditional side dishes than on the meat and poultry entrées. Grape leaves, fattoush, kibbeh and tabbouleh are available — as well as cheese sticks, fried mushrooms and wings.
