Look at these sentences:
Note that in French, there are two ways to say "something else": autre chose and quelque chose d'autre.
Now look at these questions:
Do you want to drink anything else?
Do you want to drink anything else?
Ont-ils apporté quelque chose d'autre ?Have they brought something else?
Note that you also use autre chose / quelque chose d'autre in questions, where they can also mean "anything else".
ATTENTION: in the case of questions, you won't use n'importe quoi, which literally means any thing (doesn't matter what).
See N'importe quoi = Nonsense, anything (indefinite pronouns)
