I'll tell you more details.
Siwei Chinese food and Sihaixiang are old brands with good price, service and dining environment. You can choose, and there are many stores.
In addition, you can go to Furong Seoul, where there are more than 20 large and small restaurants for you to choose from, and Sihaixiang also has stores there. In addition, Bayan language, Jingshang Food Generation and Tongzhou House are all very good.
I wish your parents a happy birthday and good health.
