Who can tell me where I can eat authentic Lanzhou beef Lamian Noodles in Taiyuan?

Taiyuan Noodle Restaurant in the south gate, Monkey Brain in Qingheyuan (Qingheyuan Hotel has been demolished, it is said that a new one will be built, and I don't know when it will be opened again), Shuangta West Street, and Green Island Caotang Restaurant in the west of Shanxi Communication Company. jiaozi is delicious, with dozens of fillings. Qingxu's home on Tiyu West Road. There used to be several Lanzhou beef Lamian Noodles shops in Taiyuan, but they all seemed to be closed. Only a few individual restaurants are authentic, not bad. There is a most authentic Jishan tofu pudding shop in the northwest corner of the intersection of Bingzhou Road and Shuangta West Street.
