Hey people, I m starting as local guide. So I think my problem is easy to solve. I posted about a restaurant and the owner answerme. He invite me to visit the restaurant again and prove the food . How can I answer him? I didn’t find the way to do this. thanks
You can not. The function allows the owner to reply to the comment but does not have a chat function. Write an email or call the owner.
Hi @LeliA
Thanks for reaching out. If you have some question like this one, you should post it into How-tos section. Idea exchange is for ideas from users on how to improve Google products. This is why I will move your post to How-tos.
About your question: Unfortunately it is not possible to answer owner directly. That is why I recommend you to just find owners contact information and send him a message where you will explain him that it is you and that you are contacting him this way. I am sorry for not being able to offer better solution.
You can also create actual Idea in Idea Exchange that this feature (being able to answer owner) should be added.
Have a nice day and thank you for your participation in the Local Guides program.
Thanks for your answer @PrzemekO .
Its a pitty . I belive that it will be interesting for users understand the all problem.
Hi @VitB
I didn’t t know these section. Next time I will put in right place.
I will look Idea Exchange too, I believe the experience with users and owners can be very rich.
I hope to collaborate as posible as I can. 
Really an interesting idea @LeliA . I’ll surely up vote your idea in that section.
