So you need to know exactly what you want to order? People rarely order food like that in my opinion. The majority of the time people like to browse menus and consider the options. In that scenario the voice chat interface is absolutely terrible. “Remind me again of the option you presented to me 3 minutes ago? No not that one, list them again. No I don’t need to know the full item description with all ingredients, just be brief!” and so on. It’s just not an efficient way to relay that type of data.
I am not sure what kind of restaurant you're thinking about where it is impossible to put every food option into an app.
If you think about the logistics of running a decent kitchen, the set is quite limited in the first place.
