Connecting Pages w/Categories

Hi,

I’m creating my first WordPress site and I’ve run into an issue I can’t figure out. The site is already set up at https://www.manayunktavern.com. The site is not a blog, but I used WordPress so that the specials could be written down on the blackboard and appear on every page. I had to create unique pages because of the static content like the photos, jquery menus, etc, but now I can’t figure out how to get a post to appear on every page. What I need essentially is to get the one daily post, which will be food and drink specials, to appear globally.

I’ve looked at some plugins that link pages and categories, but I’m not sure if there is an easier way to accomplish this. Does anyone know what the best solution is? Thanks so much.
