The best settings are where everyone is morbidly fascinated by each other.

Humans are effectively viewed as stereotypical frenchmen, constantly smoking and drinking and eating violently stinky food.
Dwarves think asbestos has a wonderful crunchy texture that goes great with a tall glass of mercury.
Elves cannot comprehend why you wouldn't simply drink raw magic like a civilized person (you gotta try some Yith'Illian merlinot, they age it for two hundred years in silverwood caskets which gives it a gorgeous silky texture).
Orcs consider most human food to be ultraprocessed slop for babies, but have become borderline addicted to our hard candy and have formed a deep friendship with dwarves over sharing bones to gnaw on.
