I think the 1910 South Railway Station you chose is quite good.

According to your requirements, within the second ring road, the price is about 1,000 yuan per table, and it also has an open-air banquet. I lived and grew up in Kunming and I can’t think of anywhere to find such a place. The second ring road is the city center, so where can I find a place to have an outdoor banquet?

I will provide you with two places that I think are good for your reference.

1. Xihua Shanshui Restaurant. The location is in the parking lot on the side of Xihua Park on the South Second Ring Road. I have participated in an open-air wedding held by my cousin there, and it felt more romantic. The wedding was in Xihua Park, and you still have to go back to the restaurant to eat. It's not an open-air banquet, but I think it would be nice to have the wedding ceremony in the park. The price may be as low as 1,200 per table. Nowadays, wedding banquets priced at less than 1,000 are basically unaffordable.

2. Shunfeng Hotel Dianchi Branch. The restaurant is located in Haidian Park at the end of Dianchi Road. In the past, it was not easy for high-end restaurants to be open under such strict state control. Now the prices are much cheaper. Companies often invite customers to eat there. The meal ordered by Meituan for 20 dishes was 698 yuan, and all 12 of us were satisfied. Didn't finish eating. The environment, food taste and service are all great, and it feels good to get free park tickets when you eat there. I saw someone holding a wedding banquet there last time, and it was very beautifully decorated.

The above opinions are for reference only. Specifically, it is better to communicate with your boyfriend more and inquire from various parties. It is still early anyway. In my humble opinion, it is best to give up the idea of ??having an open-air banquet. There are many places like this. It is not pleasant to eat in the open air. The food gets cold immediately after it is served. There is a gust of wind and ash drifts into the bowl. It is a little slow to eat. The inconvenience of wasting time in the dark is completely asking for trouble.
