1. Zhengzhou Foreign Language School opened its campus in the west. There is no Dicos there, but there is a Mai Jiamei fried chicken hamburger shop opposite the school.
2. What kind of better hotel do you mean?
There is a Debaoyu Mill, a Hong Kong-style hotpot restaurant opposite Zheng Wai. The food is ok, but the bottom of the pot is not very strong.
There are many snack bars nearby, such as Mala Tang, Rice Noodles, Huimian Noodles, etc.
3. If you don't feel enough, you can take the No.31 bus directly at the entrance of Zhengwai and get off at the Art Museum, which is very close to Zhengwai.
There are many restaurants near there, such as Xiao Ji Huimian Noodles, Lao Guan, airball trotters, Sigh Ji and so on. Besides, there is a Gabrielle supermarket nearby, and a coffee shop on the second floor is also good.
4, or north of Zhengwai, take bus No.56 or No.45 to the south gate of Henan University of Technology. There is a Youle cafeteria, which is not particularly delicious, but it is also affordable.
I hope it helps you.
