There are quite a lot of restaurants near Xuzhou Railway Station, mostly fast food, such as Haoqishui Dumplings, KFC, Xilai Soy Milk, 7+7 fast food, etc. However, if you want to have breakfast, I suggest you go to Haoqishui Dumplings, which has breakfast in the morning.
In addition to dumplings, there will also be rice-treasure porridge, glutinous rice balls, beef vermicelli soup, etc., as well as side dishes, egg pancakes, etc.
