My guests have been given the option between 2 appetizers and 2 entrees (no choice for dessert) and I would like to have a menu card on each person's place setting.
The issue I have is I would like to have personalized menus for each guest and also something visual on the menu that will cue the server (e.g., a line or an object) so that they do not need to ask the guest what they ordered. Because the menus are different for everyone, is there a way I can subtly out something on each menu that will stand out for the server and won't look out of place on the card?
Thank you for your suggestions
