Last night I went to this restaurant. I was first told about it by a friend who has traveled in Xinjiang and said that it was a Uighur restaurant, and then Sietsema gave it a good review a couple of months ago. I think that I should adjust my timing for this place, because we showed up at 8 pm on a Saturday night and were told that they were out of most items on the menu.
We ordered a potato salad, which was nice - not unusual for that dish, except nicely seasoned with dill. They gave us a carrot salad, too, which was similar to carrot salads I've had at Uzbek restaurants, although not as good (especially not as good at Registan in Rego Park). The lagman (lamb broth with noodles, cilantro, and spcies) was also not as good as lagman I had at Registan - not as flavorful.
However, the lamb kebabs were spectacular! There were two varieties, a straight-up lamb and lamb ribs. Both were tasty, juicy (alright, greasy, but in the best possible way), and flavorful.
The place actually seemed more Russian or Bukharan/Uzbek than Uighur (I am under the impression that Ramen King in the Flushing Food Court is Uighur, but I could be wrong), but whatever -- it's nice to have a good food option in Brighton Beach, where I have found it hard to find tasty food.
