> How would would you say "where is the toilet?" more succinctly with the context up front in English?

"Restroom?"

We're talking(the article) about forming sentences, not just saying words at people.

"Restroom?" is a valid english sentence.

https://en.m.wikipedia.org/wiki/High_rising_terminal you can raise the pitch to indicate that you are asking a question

While I agree “restroom?” Is perfectly valid, you could also say “the restroom is where?” Which puts the important noun first and makes it a question later. It’s not particularly formal, which in America at least is completely unnecessary for day to day life.

"The toilet - where would I find it?"

But arguably putting the key information at the start of a sentence is not ideal as it gives the listener no time to context switch. If I ask a busy waiter in a restaurant "where would I find the toilet", they may well not fully hear the "where would... " but they'll know for sure what I've asked by the end of the request. Which is presumably why we often prefix statements with "excuse me, but..." and the like...I assume that must happen in Korean too.
