Zhajiang noodles in 1988 Korean drama is one of the traditional Korean cuisines, and I believe many restaurants in Changsha also have this kind of cuisine. The following are some restaurants that I know have a good reputation in Changsha Zhajiang, for your reference:

1. Little Sheep: The address is located at Baohe South Road 188.

2. Old Changsha Zhajiang Noodles: The address is No.58 Hejiabazi, Datuo Town, Station Street.

3. Laoguanping Sauce Noodle Shop: The address is located in the southwest of LG3-02, Wanjiali Shopping Center, Juntun, Tongzipo South Road.

Of course, these are just some famous restaurants. You can try to search more restaurants. At the same time, due to the changes in time and market conditions, it is still necessary to ask whether the above restaurants still have the supply of Zhajiang noodles.
