In Hawaii the most popular form of entertaining is potluck. With the diversity of ethnic groups we have here, a potluck dinner can be a very exciting culinary event.
It is not unusual to have several relatives in one family who are of different ethnic backgrounds (chinese/hawaiian married to a japanese/american or portuguese/filipino married to a hawaiian/samoan, etc) so within one family pod you could have at least 3-6 ethnic backgrounds.
When you are lucky enough to get invited to a community potluck then the mix can be even greater, so the food brought reflects the gamut of a United Nations gathering.
The best way to eat at a potluck here, is to serve yourself little bits of everything to taste. But just in case Auntie Lehualani is sitting next to you on one side (and she made the huli-huli chicken w/poi side dish) and Uncle Yoshimura is on your other side and he brought the Miso Yaki Salmon, you must at least eat the little bits you served yourself, whether you liked it or not.
After you finished your "tasting" then it is safe to go back for seconds of what you really liked.
The same principle applies to anywhere else you live in the world. When I was small, my mom would serve us at least a small helping of everything and you had to finish what was on your plate before you could go for seconds of what you really liked. I in turn followed this practice with my kids. It is a good idea to expose them from the time they are small to all kinds of food, then they won't embarrass you when they go out to eat.
