I found this last night in my local Muslim Lanzhou Lamian Shop
Their "Xinjiang Big Plate Chiicken" came in two sizes. This is the smaller of the two and cost ¥30. They also had a ¥60 version. I was with one other person and there was no way we could get through this lot. The two of us ate about half and were stuffed. The other half is in the fridge and will be today's lunch! Doggie bag culture is alive and well in China!
As you can see, the chicken and potatoes came on top of a bed of "knife cut noodles'. The sauce contained douban jiang, Sichuan peppercorn, ginger, garlic, star anise, cloves, cumin, broad beans, caoguo (false cardamom), tomato, red and green chillies.
This is a speciality of this particular restaurant. Here is the window. From top to bottom they are offering Lanzhou Beef Lamian (Hand pulled Noodles), Xinjiang Big Plate Chicken, Lamb Jia Mo (spicy lamb in arabic style bread).
