It depends on the context! Trying to Americanize Godzilla, for instance, has largely failed because Godzilla is an allegory for the unique horror of nuclear bombing which Japan experienced. Making him just a lizard that walks through New York is kind of stupid.

Jokes are an example of something translators can do really well - things like puns don't work 1:1 across languages. A good translator will find a corresponding, appropriate line of dialogue and basically keep the intent without literally translating the words.

Food is kind of silly because it's tied to place - if a setting is clearly Spanish, or a character is Spanish, why wouldn't they talk about Spanish food? Their nationality ostensibly informs something about their character (like Godzilla) and can't just be fine/replaced.
