Good day,Does anyone know how and where

Why can you not just email, or better still, call them?

I sent an e-mail one week ago and haven’t heard back. I noticed on the web today that the official opening of the hotel is in april 2019 and it seams that  we can start making reservations in January 2019.  I guess we’ll have to wait until then.Thanks for your help,Cindy

They are closed until 2019 which is why you likely have not gotten a reply.  If you go to the ristorante website you can see the details.  Also, they have a "Book" a table button (currently in active as they are closed until 2019) which is easy to use once it is reactivated.  Although I find it just as easy to learn just a little Italian and phone for my reservations.https://www.grottapalazzese.it/en/ 

Thank you! I'll wait until January 2019. The book button does not permit us to reserve a table at this time.Cindy

You can book table at grottapalazzese .it directly from the website. But before booking the table, I am suggeting you to read our review.As many have stated the view is gorgeous, it stops there though.The food is just average instead of fantastic, as you'd expected it to be by the price you're paying for. The food "would be ok" if the staff were more friendly though.The service is horrible, not even a single employee was smiling, everyone seemed to be on a bad mood.Terrible experience for such a high cost. You can instead try Taco Bells. Moreover, You can also get chance win $500 if you take TellTheBell survey.
