How do you advertise the daily menu without looking like spam?

The daily menu is advertised once, with the dishes and the kitchen’s hours, to people nearby who have not come in today. Do not repeat it every hour to the same area if they have already seen it. Send today’s dishes before the hour the ad is switched on, not the next day. The same text runs morning and afternoon and the neighbour feels it as a notice that will not stop. An ad dated for a single day, a morning window and a pause when the kitchen stops that menu.
