Placement of characters in a simple question I am really struggling with knowing where to place words in a sentence. In particular, I was trying to formulate some sentences using 什么 and the sentence 'What do you want to eat for lunch?' popped into my head.

So I was trying to write this in Chinese, and am a bit stuck.

I initially wrote : 你午饭要吃什么？

But that seems wrong and unnatural to me. Either like there is something missing or I have the characters in the wrong place.

I thought maybe instead : 午饭你要吃什么？

But that is certainly wrong. I am pretty sure that 你要去哪里吃午饭？is correct (hopefully my intuition is correct!), but in the same vein I can't quite figure out what would be wrong with 吃午饭，你要去哪里？

I can also think of 你在哪个地方要吃午饭？

But obviously these all mean something different to the original- these talk of place and not 'what do you want to eat'. I am still stuck on the original sentence!

Also, I have seen this SE post, but I am still unsure with regards to my specific question.
Both你午饭要吃什么？and 午饭你要吃什么？are right

These two sentences all mean what do you want to eat

“你要去哪里吃午饭 ”is correct in grammer，but it means where do you want to have lunch，it does not means what do you want to eat

吃午饭，你要去哪里？Although we can understand what the sentence mean,we simply don't speak this way

你在哪个地方要吃午饭？should be: 你要在哪个地方吃午饭？
