Post today's specials to Google Business Profile every morning

Each morning before opening, add a Google Business Profile post with the day's special, a photo of the dish, and the hours you're serving it. Do this five days a week using your phone and the Google Business app, and keep each post live until you swap it the next morning.

Why it works: Google Business Profile posts show up in local search and Maps results, so people searching for lunch nearby see what you're serving today.
