Which goal do you choose: visits, messages or a completed booking?

You choose messages if the booking is closed on WhatsApp and someone reads them. You choose a completed booking if it happens on a page that really confirms the table, and visits only if there is no other way to see the menu. Say where the table is closed today: message, phone or page. Visits are asked for and people land on a site with no hours. The goal written beside how a booking is actually taken.
