How do you prepare an opening campaign?

You advertise the date on which a booking can already be taken, with the photo of the dish you will actually serve that day. The campaign does not go out if the works are still on and nobody is answering the phone. Confirm the day, the hours and who replies to the booking message. The ad asks for a booking and at the door there is still no service. One ad with the date, the photo of the real dish and the booking link tested.
