Now I have a question about where i should put the word "all".

I was working on the word order problem:

( these / all / dishes ) look delicious.

I wrote "All these dishes look delicious." as an answer, but the correct answer was "These dishes all look delicious."

According to my reference book, I think mine is also correct.

Now I'm wondering

1. which one is better (or natural)

2. what is the difference between mine and the correct answer

Could somebody help me out?

Thanks in advance ;D

As a non-native speaker of English, I often stuck in the logic I don't have, but native speakers may have.

I always want not just the answer, but the reasons why native speakers choose the expression.
