You can put your menu on Google maps, we did it for our restaurant. https://maps.app.goo.gl/YdbSHd7hewkXQeMz8 see "menu" tab

To be fair the Google maps restaurant side of the operation is quite possibly the largest ratio I've ever seen between "amount of capital and engineering skill available" and "quality (lack thereof) of UX." You have to access your restaurant profile through the Google search portal. It's a nightmare.
