Thank you for your kind feedback. The reason for a warning command because I found this post was insufficient and lacking in detail about the food/drinks and restaurant. I was trying to help you to improve your post by giving a suggestive question on how and why this restaurant is good to bring friends if the food or drink in this restaurant is not recommended.
Logically speaking, you won't bring your friends to a restaurant/cafe that serves bad food and drink and you can't just sit there without ordering anything just because the restaurant/cafe looks good. This will help you to enlighten the readers and other Tasteemers.

The rules included in the comment were meant to be a standard layout.

You can take the suggestion and improve your post or leave it. However, having a good post will likely to get you a curate command and thus resulting in a bigger upvote. I only tried to help.
