After reading numerous posts about Helmand's, I felt compelled to visit the place to check it out for myself.
A caveat: I'm Persian, and expected Afghani food to be similar. When I heard they had Aush (noodle soup), that was all I needed to get me in there!
We had the pumpkin appetizer and aush, both delicious. The pumpkin was very different from anything I've ever eaten. My partner thought the ground beef tasted strange with the yogurt and sweet pumpkin, but I thought they were nice texturally... The aush was very similar to the persian version, and hit the spot.
Dinner didn't seem at all "middle-eastern" to me -- rack of lamb and chicken salad. They were both phenomenally good, but didn't seem very authentic to me -- but that may have been my prejudice. The only thing that was close was the spiced polo (rice) which was lovely.
Dessert was VERY authentic baklava, middle eastern- style with cardamom (which Greek baklava doesn't use), and turkish coffee.
Even had time to read the grounds, which told me that my future "holds many delicious meals"! Thanks Chowhounds!
