How to show both locations of my business on google side by side

Hi, I wondered if this is an issue with SEO, but I have two restaurants relatively close. When I search its name on Google, only the first location shows up that we ever opened. The thing is I want both locations to show up side by side so they, my customers, can choose which location they want to go to. Also yes both of my locations have their own GMB pages with the same website attached to them.
