If you are inviting customers, order some decent "big dishes", which will not only keep up the scene, but also give the leader a long face.
If it is an internal gathering, we should first consider the taste of the leader and the preferences of other leaders.
Be sure to know in advance whether the participants have any taboos (such as Muslims)
Whether to drink or not depends on the occasion. It is natural for customers to drink too much, and they should also be prepared to lead themselves to give up drinking.
Eating internally depends on leadership and drinking well. If you like to drink, you can drink more bottles, and if you don't like to drink, you can drink a few cups symbolically.
A hearty dish should include appetizers, hot dishes (with vegetarian dishes), a fish and soup, and a cooked fruit platter.
