As for what can be done in 700 yuan, I think it needs skill. For example, the collocation of dishes can be communicated with the hotel in advance. I think 20 people need at least 18 dishes. Now you can talk to the hotel about bringing your own drinks. (However, you should reserve a private room in advance. In addition, there are exquisite skills when serving. For example, when serving food, you must not pass chopsticks first. In that case, one dish will be ruined, and soon you will find that even 30 dishes are not enough to eat. Be sure to pass chopsticks in the middle of eating, so that 20 dishes are enough to eat. Also, before serving, some sweets and melon seeds should be served. Some lesbians are greedy and will definitely eat sugar first, which is more economical. Why else should melon seeds and candy be served before the wedding reception? That's the reason. Also, the ratio of men to women is also the key to saving money. It is very expensive for a woman to eat without drinking. I believe if you follow my method, it will save you a little.
I personally recommend you to try the Tianyou Hotel.
I hope I can help you!
