Look at your budget and recommend one that is popular all over the world. In the harmonious era, there are about ten people at a table, which is about 800- 1000 (this is our department's dinner, 1 1 person, starting at 750, plus 950 dishes, including drinks and beer). Besides, Hunan food is not bad. I don't know your exact location. If you want to be better, it's better to be near Rong Yuan, Zuo 'an and Gong Li Dam, and there are Laowudong, Laobeimen and Harbour City nearby. If you think it's still expensive, you can see what good shops are around. There are still many good shops in Suzhou.
Suggestion: Because there are not many of you, you'd better order your own food, and don't let others side dishes or anything. It's not cost-effective to book a table or something.
