Google now lets you add to your restaurant's menu within Google Business Profiles. Previously, I believe you were only able to replace your previous menus, but now you can add to them by uploading the new menus.
This change was spotted by Claudia Tomina who posted a screenshot of this new feature on both Bluesky and X - here is that screenshot:

Making these things easier for restaurants and small business owners is a great thing and I am happy to see this in Google Business Profiles.
