For Xi'an's ground pot chicken, I only remember that Xiaogui Xiao ground pot chicken is pretty good and it's a chain store.
There are branches on Fengcheng 5th Road, Guodu, Greenland Century City, Gaoxin Road, Nanda University Town, Laodong South Road, etc. Friends who want to eat can try it. The price is very affordable and suitable for four people or less.
