There seems to be nothing good to eat around Tianjin Station, but the night view of Jinwan Square is very beautiful at night. You must see it. It is just opposite the train station, and you can also take a look at the Haihe River.
For food, there are many on Binjiang Road. In addition, you can also buy specialties from Binjiang Road. The Guishunzhai main store is at No. 101 Heping Road (at the intersection of Fu'an Street). There is also one on Xinhua Road. Just look for it on Baidu Map.
Scenic spots include Porcelain House, Binjiang Road, Xikai Church, Xiaobai Building, Five Avenues, Italian Style Area, Eye of Tianjin, and Ancient Culture Street.
These distances are not that far.
On the first day, I walked around the ancient cultural street, which is quite lively during the Spring Festival.
If you are interested, stop by Nanshi Food Street. You can find delicious food and specialties, but the price is a little higher.
In the evening, go to the Italian style area for dinner and see the night view. You can also go to the Tianjin Eye.
The next day, we walked around the Five Avenues. It would be better to find a carriage that would tell stories or something more interesting. In the afternoon, we would go to Binjiang Avenue.
