Call the hotel during the business day and ask for the concierge. Explain to the concierge what you want done. I will be surprised if he does not accommodate or explain why he cannot do what you ask.

As others note, if you have not called the restaurant yourself, you should not presume that there is not an English-speaking staff person to take your call.

For the benefit of others, if you send emails to a property, make certain that you are emailing the correct person. Generic mailboxes often get misrouted, not answered or misunderstood.
