Although the restaurant started as a sushi place, it serves really authentic Ningxia food. The owners originally came from Ningxia, China. I went to seveal states in USA, but rarely found these kinds of dishes. Even in China, it is hard to get authentic Ningxia food.
I always get the BBQ pork sandwich(Rou Jia Mo) The Rou Jia Mo is stuffed with tender strips of meat, onion and more.... It's a treat!
I also recommend trying their variety of noodle dishes. The noodles are all hand made and fresh.
If you love lamb, you have to try their lamb dishes. Lamb is Ningxia's famous traditional food. They serve lamb braised in soy sauce, lamb steamed in clear soup and so on. The meat is so tender and tasty. The prices are also unbeatable. They are around $15 for a big portion.
