If there are more men and the overall appetite is large, I think 13 to 15 hot dishes and 4 to 6 cold dishes are more suitable, and you can have another soup.
If there are more women and the overall appetite is not very large, 9~ 12 hot dishes and 3~6 cold dishes should be enough.
Of course, if you have bulimia, you can order 15~ 17 hot dishes and 4~6 cold dishes. If you want to eat everything and eat a lot, 1 1~ 13 hot dishes and 3~5 cold dishes should be economical choices.
Also, I think the most important thing is not how many dishes to order, but whether it suits everyone's taste. If you don't want more than two-thirds of any dish left in the end, you'd better not eat too many cold dishes.
Pure individuals have an average of three meals a week 1. I hope everyone can refer to it!
