At present, the catering provided by most sites is mostly chain brands. For example, the restaurants that can be booked at various stations in Nanjing include not only the meals prepared by the railway, but also the old uncle, King Yonghe and Kung Fu.
The catering brands of the other 26 sites are also mostly chain brands in the station. For example, hangzhou east railway station, thousands of Lamian Noodles and Dicos; There is Yoshinoya at Changchun Station. However, if you want to eat "special food" along the way, it is not impossible.
For example, at Changsha South Railway Station, you can order braised pork, chopped pepper fish and small fried meat. Hangzhou east railway station can order Wufangzhai Zongzi; Tianjin West Railway Station can also order Goubuli buns; Xi' an North Station has Chinese hamburger; There are Sichuan-style pork and spicy chicken in Chengdu and Chongqing stations; Zhengzhou East Station has mutton Huimian Noodles and three counties Huimian Noodles.
I hope that more sites will open online ordering service in the future, so that more people can eat some local specialties.
